Since the plastic walls are rather thin, I would put a metal washer or some self-made one from a scrap piece of plastic between the jacks and the walls on the inside. Helps to distribute the forces from plugging in and pulling out so you don't end up cracking your housing.
@@jonrogers1497 the Ex has line out but it’s not speaker out, it’s for recording. The impedance of a line out jack is much higher than a speaker jack, it won’t drive a speaker.
TIP: When soldering the speakers turn the amp on its side so the speakers are facing down. If any solder drips then it wont drip on to the PCB. Better still try and re-use the speaker connectors that were cut off at the start or buy some new ones (it will be worth it). If you have to solder: Do it outside the amp.
@@TheGuitarGeek it's a warranty void already anyway don't sweat it and get Boss to send another one ahahahahaha!! I'm sure they're having a laugh while also biting their fingers all the way to the end of the video lol!!
Finally you did the mod! Thank you!👍🏻 I think the Air is still a perfect practice amp! I have the normal Katana 100 but I still often use the Air to practice!
Thanks, I just did this modification to my Katana Air and it sounds great. I was considering selling it and getting the Katana Air Ex but opted for this mod instead and I am super happy with the result.
Great video. When I was a kid I did this with my Boombox so it could drive large speakers at home but could still be used portably. It worked almost exactly the same as you showed in this video. You could probably do this with just about anything with stereo speakers on it.
OG hero- love the scarlet ghost avatar to boot. was the boombox the one with little speakers that popped off to spread out when parked at home, with the pull-out tape deck you could use as a walkman? (ie shockwave the decepticon) ... had that on my uncle's old speakers held together with electric tape until i learned to solder- thanks radioshack!
the new EX is the same amp with bigger speakers. Im now wondering if I should re house my air into a new wooden cab ad go one better than the EX and use 6.5 ich speakers
Warranty void! Awesome video Andy! It always blows my mind a bit that the speaker in the signal chain makes such a difference. It’s often an afterthought. You’d never guess you were playing a tiny little home practice amp. I’d love to see a comparison between the Katana Air and the Spark.
I will be back with more Katana answers!

Warranty void!! Thanks Andy for your demonstration and the mods you did a perfect job I thought the speakers might have blown but brother you pulled it off! Have a wonderful day mate!
Warranty definitely voided! Fun vid Andy, thanks! I recently ran the amp out to newly installed external speaker socket on a 5w/8" spkr Champ wannabe and ran it through a 12" Celestion G12H cab (not forgetting to use speaker cable and always making sure either the 8" or 12" speaker was connected to give the amp load). Amazing how loud 5 tube watts can be, especially in a cab with lots of air - so best of both worlds, either funky boxy 8" or bigger cleaner louder 12"...simple cheap mod with big payback. Cheers
Very cool mate, well done. I love how you have spazzy different coloured wires everywhere because it's just what you had laying around at the time. I do the same. I been watching your vids for ages but only just noticed I wasn't subscribed, so now I am. And warranty void!
Did this to a late 90s Kustom reissue tuck n roll combo a few years back and it has been one of my favorite amps since. Run it through eminence swamp thangs and it is so loud.
Correct me, if I'm wrong, but I think, that it is also important to use external cabinet of same impedance as internal speakers are of. Otherwise you could damage the power amp section.
Ok, question. If i have a 100 watt amp driving 1 speaker you get a given volume. If you run 4 speakers to that same amp does each speaker only put out 25% of the volume? So is 4 actually louder or quieter than 1.
Great video - as always on your channel! In your Thomann-Parts-List you have referenced a wrong jack socket: it should be NMJ4HC-S instead of NMJ2 HC-S which is not switchable and not available at Thomann Germany.
Thank you for the confirmation of my idea for that exact mod to my Blackstar ID Core 40 stereo amp which I got for under $100 a couple of years ago. Another few bucks and I'll have a more versatile amp which I plan to plug into my surround system for a more well rounded sound.. I only play in my room so this along with a switching box I'll custom build for the purpose, will do the trick quite nicely thank you. and Yes the sub woofer is included in the surround system. Actually there two subs so a bit of boom boom from a my guitar may be there too..
Warranty void! For such a simple mod that so cheap to do at home, I'm really surprised that Boss didn't do this from the factory because with their economies of scale it would cost them even less! Although maybe a purpose move to not overlap with their own other products?
What about delivering the output signal through the headphones / rec out socket through an amplifier and to some larger speakers? No drilling, no soldering, no warranty void...
I’m very impressed that it works so well and was so loud. Yet I’m Disappointed that Boss doesn’t have a single jack for external Speaker cabinet to be used . Would make this traveling amp near perfect idea. This might change my purchase of this amp.
Warranty Void! great vid, prob going to install this mod. Makes me think if I can mod my Spark Mini too. The speaker is great if you're at the perfect angle and distance, for gig's a real cab at 20/30W would be great! I need to figure out how to mod to toggle the Aux out of muting n unmuting the internal speaker. Would be perfect with my GoPro for nomadic shredding n shooting, if i could hear myself while recording ^_^ splitting to an aux speaker has been a workaround but another speaker when there's one built it, ya know! Rock on!
Nice mod. Another option would be a stereo/mono auto connect - one cable mono with both channels, two cables stereo. Also, the speakers in Air is not guitar speakers. I would like to hear your mod into FRFR speakers, like studio monitors or a PA. Another interesting mod would be: removing the speakers, put the electronics into a small box. Powered by a boss plug, center neg from a power supply. Voila, a pedalboard amp!
I did this mod with a cheap Behringer 30W practice amp I got a while back for something to do. FYI the internal speaker sounded like a$$. Worked out fine. Ran it into my Marshall 4x12 for kicks, and it sound like a$$ through a 4x12 ;)
Need external speakers because near impossible to get away from small plastic box sound of internal speakers. Years ago I put a similar mod to my Vox AC1 (9 v battery, 1 watt with a tailwind). It drove my friend's JBL PA speakers surprisingly well. Thanks for vid
The warranty void is a bad thing. Actually, my HB-80R has a mono out to a cabinet. I don't know what it is, but to me, this sounds like cheap little plastic speakers. I know it's not the HB-cab, that actually sounds great, so there must be a different reason.
The reason is that the speakers on the Katana Air are most likely hi-fi speakers, not guitar cabinet speakers. So the guitar cabs are receiving the signal that was tailored to a very different type of speaker.
Warranty void any of my apps that aren’t wired I wire them I have a 20 W fender champion that I can plug into my 2 x 12 and then I have a vox Cambridge, which I can plug into my 2 x 12
The Thomann link to the parts used shows the wrong set og Neutrik inputs with two slugs instead of four. I ordered unfortunately via the link. Major bummer.
Clever. No one should ever try this WARRANTY VOID, but could you do this mod without soldering if you just put the quick connect terminals on the new jack and a second set of wires with quick connect terminals from jacks to the internal speakers? Or would the quick connect terminals not work on the new jack? Thanks for sharing.
I tried that at first but the spades did. It fit as one side was too small. Buying new spade connectors is an option of course but I won’t be undoing this mod on my amp
I use an 1/8" to 1/4" adapter in the headphone/record out port. Keep the volume on the katana air low for better sound quality (because it's solid state) while using the other amps volume to crank it up. Or use an aux chord. You can run it through a home stereo system, car system or whatever. Perhaps a Bluetooth adapter would work in other scenarios. I've even used a cassette adapter. Be advised that if you're playing through something other than an instrument speaker it may cause damage or failure if you run it too loud
They can be found virtually everywhere and have been used/sold for decades. An aux chord is an 1/8"×1/8" male to male chord. Some car stereos come with a port for these. You might find one at any dollar store or even gas station. The 1/8" to 1/4" isn't as easy but Walmart or bimart should have it. You can plug an aux chord into it and it turns the 1/8" male into a 1/4" male for house stereos or whatever. The cassette adapter looks like a cassette tape with a wire coming out and a 1/8" male plug on the end. Helpful when connecting to older house and car stereos. Walmart or bimart might have them. If any of these places don't Amazon will. If you live somewhere where sound is illegal these adapters make it possible to drive to open space and play as loud as you like. If you just want to piss off all the crybabys in the campground or electronics department of a store by playing live punk rock or metal or maybe draw attention to yourself in an unfamiliar town by performing through a car system these adapters make all that possible. Adapters make it possible to use otherwise outdated equipment which is nice because the "outdated" stuff is louder more reliable and higher quality not to mention plentiful and cheap. Be warned...companies are writing programs that block adapters. That's why cell phones have never had a "line out" port. They want to sell you internet for your house, your phone, and your car instead of using one connection. They want to sell you cable even though you can watch everything you ever wanted on your phone. And lastly they want your bank credentials, the ability to track you, and the ability to sell their crap to you wherever you are. That's why analog should remain. It's done a wonderful job broadcasting video and sound for more than a century and is still working just fine without needing a credit card.

I'm looking forward for your take on the Katana Air Ex. They have put an official battery mod, and a line out on it, but no speaker out, wtf why!? This is nonsense and so frustrating. The neat thing would be a mono 8ohm output instead of 2x4ohm. So far so good, I'll probably try it on my Ex (the amp). It's so frustrating how it's good and still miss that one little thing that would make it legendary, Dammit Roland! Thank you a lot, you are by far one of the most useful and cool youtuber I'm watching.
Warranty Void. I possibly should have watched this before I bought my Katana 50EX - which I chose because I've been very happy with the Air. I miss the wireless feature too. I'm going to buy a set before I trip over the guitar lead. 😜
Have done something similar to a Laney LX12 practice amp I have a few weeks back. Just added an effects loop between its preamp and power amp and alsolso, added a speaker out jack. No joy is more that the tone I get from this amp now and some basic pedals, not even the tones of the Katana 100 mkII 🤣 Self modding is a joy as long as you acknowledge the risks 🤣
Warranty void. I did this to my Katana mini(after watching your video) and a Vox Pathfinder 10. Because the Pathfinder 10 has an 8ohm stock speaker, it drives my 1x12 cabinet really well.
The amp will probably be giving out less power driving the 8ohm cabs, so you will be gaining speaker cone area but loosing wattage. Also, the katana will be voiced for it's internal speakers. Warranty Void!!!
04.Aug/2022 If you are looking for a Bluetooth pedal that can control the Katana Air, here's some clarification: When switching the sound from crunch in mode 2 to clean with the Airstep BW on the panel, the Xsonic Airstep BW needs up to 1 second to switch from crunch to clean sound, which is too long for me personally! The Airstep Update App also runs stable on Android, but the update almost always fails! I can only recommend the Airstep BW if you accept that the switching time is 1 second when switching to the clean channel on the Katana Air's panel. The problem is not with the amp but with the Xsonic Airstep BW Bluetooth controller pedal. Besides this one latency switching problem, the Airstep BW controller is very good! Xsonic manufacturers: Can you fix this issue in the next update? Good to know: The Boss Katana Librarian App does not support the Katana Air! Can Roland- Boss solve the problem? Question for you musicians: Have any of you tested the Boss EV-1-WL with Boss FS6 or FS-7 and what is the switching time before switching the Katana Air? Thank you for your willingness to help. (guitar teacher and repair service)
I have an old Fender Frontman 212R that died and I would like to turn it into a stereo cab for one of those Katana Air amps. How do I ensure the ohms are proper so I don’t fry something?
Check the impedence of the speakers. it may be written on the speakers or search official databases for it. The best way would be to get it measured. There are videos on TH-cam for how to do that yourself
Great video. Up to me there should be more of this ‘don’t do this at home’ videos for those who have thoughts on modifying one of the Katana amps (and who are a bit stubborn of course :-) ). A thought I have is adding a send return out and in to the Katana 50. The ‘in’ is there,, but when using, the signal from the preamp and effects is disconnected. This signal is however still available and it must be possible to lead this signal out via a jack (which will create the send signal). Any thoughts on this noughty idea? B.t.w. In this video. Switching only both red wires would have been sufficient to do the job. For those who have already single switching jacks on the shelf.
@@TheGuitarGeek Haven't done it yet. I didn't even know that kind of bypass jack/socket existed prior to watching your video. My first plan was to disable the built in speakers completely and just connect the speaker mains to a regular 1/4 inch jack.
Warranty Void. Cool mod but isn’t the speakers in the Katana Air FRFR speakers? I’m not sure, just asking. If they are, wouldn’t this mod be better served by using a PA speaker?
An observation : If the internal speakers are full range ass boss states ,it means the amp should have some sort of cab emulation going on (otherwise it would al sound awful) if that’s the case ,it shouldn’t sound very good into an actual guitar cab (a cab sim into a real cab usually sound muffled ) So how’s about that??
Can someone please explain to me why people buy a small practice speaker amp combo then still end up passing it through another larger speaker combo to play it? I see that on all the youtube videos? Why don't you just stick to the big speaker combo amp you already have then?
@@Shoggy56 my apologies, the way you phrased came across quite sassy. Saying that ALL the TH-cam videos are doing this makes your question seems less genuine. I can’t speak for others but my reason is purely experimental.
@@TheGuitarGeek I didn't mean to be rude either. I just bought a Katana Air as well and i play through its's 3 inch speakers. It's a nice amp but i kind of expected more from it. Thanks for the review anyway. I just subscribed. All's well that ends well :)
my spark 40s getting some tone holes :-) how big a bass cab could you power with a 40w, though? harley benton cabs here i come - was scared of the 4/8/16 ohms bit, but WARRANTY VOID! sign me up
Warranty Void I like the Yamaha THR series but it lacks an FX loop. There are mods to do it, but it looks very complicated. Perhaps that should be your next video... show us exactly how easy or hard it is.
You could have got micro spades to put on the 1/4" connections and no soldering. The only other issue is there is no way to switch the channels on this amp while you're playing. If someone had a way to do that via another 1/4" jack and pedalboard that would be pretty cool This is where Boss really failed to deliver what home and practicing guitarist really need. As well as being able to take to rehearsal instead of lugging a heavy tube head with you all the time.
...I'm getting ready to purchase a boss katana air for practice purposes. When I do get it you can be sure I'll be doing this "Warranty-Void!" Speaker out Jack Mod! For sure! My only question is witch 2×12 cabs I'll be using with it!?
Warranty void! I'm planning on doing the same mod to an old Vox valvetronix because the alleged out via the headphone socket bypasses the valve stage... and I usually switch it to manual and use it as a barebones regular amp. Because I can!
Why don't you use the headphones/rec out connector on the top of Katana air and plug in it an adaptator cable (1 mini jack TRS 3,5 mm male to 2 jacks TS 6,3 mm male) ? it cuts the internal hps when connected. No warranty void then...
This is interesting. But why not just use the record out and plug into the front of house mixer? I haven't tried it, but I can't see any reason not to. Oh yeah... Warrenty void
Side question? As far as the katana goes I think it's a great little amp. However, when I'm using the included wireless transmitter, I have almost NO sustain. If I use a cable, it's fine. In fact if I use a separate set of wireless transmitters it's fine. There's something about the katana transmitter that just sucks. I'm wondering if it's just MY katana or is this ALL katana air transmitters?
So what would happen if the resistance of the speakers was unmatched? If I plugged one speaker into an external 16 ohm cab with 10 inch speaker and left the other running to the internal speaker? Bad idea?
I think the biggest issue is that the Katana Air is likely voiced for it's tiny enclosure and speakers, running it through big cabs may make getting a decent sound difficult.

Since the plastic walls are rather thin, I would put a metal washer or some self-made one from a scrap piece of plastic between the jacks and the walls on the inside. Helps to distribute the forces from plugging in and pulling out so you don't end up cracking your housing.
Hopefully, Boss has taken note of this mod and decides to make it a standard feature. Brilliant.
Because it's brilliant they will be certain NOT TO DO IT. LOL How would they sell anymore 100's?
Necroing a comment to say they did with the new Ex, it looks like.
@@jonrogers1497 the Ex has line out but it’s not speaker out, it’s for recording. The impedance of a line out jack is much higher than a speaker jack, it won’t drive a speaker.
That will take $3 off their profit margin, so don't count on it.
Absolutely brilliant, can’t wait to try it out. Will this also work for the Series 1 katana 50?
TIP: When soldering the speakers turn the amp on its side so the speakers are facing down. If any solder drips then it wont drip on to the PCB. Better still try and re-use the speaker connectors that were cut off at the start or buy some new ones (it will be worth it). If you have to solder: Do it outside the amp.
Thanks! I do need to improve my soldering practice. I guess I was lucky this time
@@TheGuitarGeek it's a warranty void already anyway don't sweat it and get Boss to send another one ahahahahaha!! I'm sure they're having a laugh while also biting their fingers all the way to the end of the video lol!!
Another tip, use your friend’s Katana (刀). Maybe not your best friend.

So far so good, I'll probably try it on my Ex (the amp). It's so frustrating how it's good and still miss that one little thing that would make it legendary, Dammit Roland!
Thank you a lot, you are by far one of the most useful and cool youtuber I'm watching.
Hey! Glad you’re enjoying my videos. I’ve already reviewed the katana EX. Cracking amp!
Also could you just make a mono speaker out by connecting your 2 speaker cables to one socket, would then it be still just 4ohms 🤔🤔😊👍
Hello,
I want to buy Boss Katana 50ex or 100 but I must connect a mic to it. İs this possible?
great experiment🤩🤩...thank u🙏🙏🙏 great video👌👌👌
Warranty Void. I possibly should have watched this before I bought my Katana 50EX - which I chose because I've been very happy with the Air. I miss the wireless feature too. I'm going to buy a set before I trip over the guitar lead. 😜
I don't need it to be stereo. Could I rewire the two internal speakers in series and then output to one 8ohm speaker cab?
How can I use the rec out to record direct but hear myfelf through the amp ? Boss mutes the amp every time u connect a cable to the rec out...
Thanks for this I will be doing this to mine❗🤘
So... I have just used recording out to mixer's line in and played it through the huge speaker. No mods needed :DDD
Have done something similar to a Laney LX12 practice amp I have a few weeks back.
Just added an effects loop between its preamp and power amp and alsolso, added a speaker out jack.
No joy is more that the tone I get from this amp now and some basic pedals, not even the tones of the Katana 100 mkII 🤣
Self modding is a joy as long as you acknowledge the risks 🤣
It's nice to see Quinns from Shut Up & Sit Down plays guitar! 😂
Have they fixed the App yet?
Hello, Can I also use the small phone jack to connect a cabinet speaker?
The Warranty is VOID! Great video.
Warranty void. I did this to my Katana mini(after watching your video) and a Vox Pathfinder 10. Because the Pathfinder 10 has an 8ohm stock speaker, it drives my 1x12 cabinet really well.
The amp will probably be giving out less power driving the 8ohm cabs, so you will be gaining speaker cone area but loosing wattage. Also, the katana will be voiced for it's internal speakers. Warranty Void!!!
Warranty void!!
Great mod and great guide how to do it!!
Warranty void!! Can I connect it to my Hughes and kettner 212 16ohm cab ?
Use a shop vac under the hole you are drilling to avoid plastic bits going everywhere.
LMAO - I love the Jeremy Clarkson impression at the beginning... "In the worrrrld..." :D
If I connect it to a 50 watt cabinet with power amp, will it work and sound good?
04.Aug/2022 If you are looking for a Bluetooth pedal that can control the Katana Air, here's some clarification:
When switching the sound from crunch in mode 2 to clean with the Airstep BW on the panel, the Xsonic Airstep BW needs up to 1 second to switch from crunch to clean sound, which is too long for me personally! The Airstep Update App also runs stable on Android, but the update almost always fails! I can only recommend the Airstep BW if you accept that the switching time is 1 second when switching to the clean channel on the Katana Air's panel. The problem is not with the amp but with the Xsonic Airstep BW Bluetooth controller pedal.
Besides this one latency switching problem, the Airstep BW controller is very good!
Xsonic manufacturers: Can you fix this issue in the next update?
Good to know: The Boss Katana Librarian App does not support the Katana Air! Can Roland- Boss solve the problem?
Question for you musicians: Have any of you tested the Boss EV-1-WL with Boss FS6 or FS-7 and what is the switching time before switching the Katana Air?
Thank you for your willingness to help. (guitar teacher and repair service)
Warranty void! So it still works as a practise wireless amp but can be plugged into a cab and the internal speakers of the katana disengage?
I have an old Fender Frontman 212R that died and I would like to turn it into a stereo cab for one of those Katana Air amps. How do I ensure the ohms are proper so I don’t fry something?
Check the impedence of the speakers. it may be written on the speakers or search official databases for it. The best way would be to get it measured. There are videos on TH-cam for how to do that yourself
anyway to get pedal switch? that's the only thing i miss in this practice amps :(
Great video. Up to me there should be more of this ‘don’t do this at home’ videos for those who have thoughts on modifying one of the Katana amps (and who are a bit stubborn of course :-) ). A thought I have is adding a send return out and in to the Katana 50. The ‘in’ is there,, but when using, the signal from the preamp and effects is disconnected. This signal is however still available and it must be possible to lead this signal out via a jack (which will create the send signal). Any thoughts on this noughty idea? B.t.w. In this video. Switching only both red wires would have been sufficient to do the job. For those who have already single switching jacks on the shelf.
Cool vid! Exactly what I am doing to a Blackstar LT15.
Great idea! Would love to know how you get on
@@TheGuitarGeek Haven't done it yet. I didn't even know that kind of bypass jack/socket existed prior to watching your video. My first plan was to disable the built in speakers completely and just connect the speaker mains to a regular 1/4 inch jack.
Warranty Void. Cool mod but isn’t the speakers in the Katana Air FRFR speakers?
I’m not sure, just asking.
If they are, wouldn’t this mod be better served by using a PA speaker?
Basically use rec out and some actives...or 8" PA/hifi mid woofers with this mod for some battery powered toy vibes.
Instead of solder, why can't we just use the same metal clips you unplugged from the speaker, would that work or does it have to be soldered?
An observation :
If the internal speakers are full range ass boss states ,it means the amp should have some sort of cab emulation going on (otherwise it would al sound awful) if that’s the case ,it shouldn’t sound very good into an actual guitar cab (a cab sim into a real cab usually sound muffled )
So how’s about that??
Can someone please explain to me why people buy a small practice speaker amp combo then still end up passing it through another larger speaker combo to play it? I see that on all the youtube videos? Why don't you just stick to the big speaker combo amp you already have then?
Because we are free to do so if we choose to
@@TheGuitarGeek I expected a more sensible answer from you. That was a genuine question.
@@Shoggy56 my apologies, the way you phrased came across quite sassy. Saying that ALL the TH-cam videos are doing this makes your question seems less genuine. I can’t speak for others but my reason is purely experimental.
@@TheGuitarGeek I didn't mean to be rude either. I just bought a Katana Air as well and i play through its's 3 inch speakers. It's a nice amp but i kind of expected more from it. Thanks for the review anyway. I just subscribed. All's well that ends well :)
my spark 40s getting some tone holes :-) how big a bass cab could you power with a 40w, though? harley benton cabs here i come - was scared of the 4/8/16 ohms bit, but WARRANTY VOID! sign me up
Warranty Void
I like the Yamaha THR series but it lacks an FX loop. There are mods to do it, but it looks very complicated. Perhaps that should be your next video... show us exactly how easy or hard it is.
Be bloody careful of a warranty void situation mate. Super cool dude👍
Thanks for the heads up!
You could have got micro spades to put on the 1/4" connections and no soldering. The only other issue is there is no way to switch the channels on this amp while you're playing. If someone had a way to do that via another 1/4" jack and pedalboard that would be pretty cool This is where Boss really failed to deliver what home and practicing guitarist really need. As well as being able to take to rehearsal instead of lugging a heavy tube head with you all the time.
I guess that’s what the katana head is for
...I'm getting ready to purchase a boss katana air for practice purposes. When I do get it you can be sure I'll be doing this "Warranty-Void!" Speaker out Jack Mod! For sure! My only question is witch 2×12 cabs I'll be using with it!?
Has anyone figured out a way to use a pedal to switch channels/effects on the katana air?
Warranty void! I'm planning on doing the same mod to an old Vox valvetronix because the alleged out via the headphone socket bypasses the valve stage... and I usually switch it to manual and use it as a barebones regular amp. Because I can!
Hello just question is it ok to connect two 4ohm speakers externally thanks , your casts are great 👍 thanks 😊
Warren T. Voyd would love this mod.
Why don't you use the headphones/rec out connector on the top of Katana air and plug in it an adaptator cable (1 mini jack TRS 3,5 mm male to 2 jacks TS 6,3 mm male) ? it cuts the internal hps when connected. No warranty void then...
Maybe the amplifier for the headphones is less powerful than the one for the internal hp's
Warranty Void. Wow. Amazing volume. Many of my best (& worst) experiences, started with focusing on 'don't try this at home'.
Say could I do something similar to my Blues Jr? Not stereo of course but I always wanted to run it to a 2 x 12.
This is interesting. But why not just use the record out and plug into the front of house mixer? I haven't tried it, but I can't see any reason not to. Oh yeah... Warrenty void
i have a need to warranty void. Liking the channel
Cheers Mike!
So wiring one of these jacks the other way around could give the ability to use a combo as a cab... I'm gonna buy a bunch and do some experiments
Side question? As far as the katana goes I think it's a great little amp. However, when I'm using the included wireless transmitter, I have almost NO sustain. If I use a cable, it's fine. In fact if I use a separate set of wireless transmitters it's fine. There's something about the katana transmitter that just sucks. I'm wondering if it's just MY katana or is this ALL katana air transmitters?
Warranty void. The for the demo!!
Great warranty void timing! I’ve been considering doing a mod like this recently. Now I don’t have to wonder if it’s possible.
So what would happen if the resistance of the speakers was unmatched? If I plugged one speaker into an external 16 ohm cab with 10 inch speaker and left the other running to the internal speaker? Bad idea?
I think it would actually be ok but I wanted to recommend what I feel is the safest method.
TheGuitarGeek only one way to find out!
I think the biggest issue is that the Katana Air is likely voiced for it's tiny enclosure and speakers, running it through big cabs may make getting a decent sound difficult.
Warranty void.
Yes well....
But suddenly the Katana Air is back on my radar 🤣🤣🤣🤣
Right?!
Warranty void! I'd love to know how the sound compared to a katana 100
"Warranty void"? Oh, I do remember the times when your TV came with a fully detailed schematic for you to be able to fix it ...
