I Turned this Fender Bassman Amp into a Total TRAINWRECK...and that's a GOOD thing!

- เผยแพร่เมื่อ 18 พ.ย. 2020
- This is a 1968 Fender Bassman that I modded a while back for a customer with what I call my "ABNormal Channel Mods". It's a non-destructive way of taking a stock Bassman and utilizing what's already there, drilling NO EXTRA HOLES in the chassis, and bringing out the fire-breathing Master Volume Marshall or Ken Fischer Trainwreck hidden within. I was even able to add a Presence Control without drilling. This one had already gone to the customer and came back once with a "frying bacon" noise issue. I thought I had fixed the problem and everything was 100%, but nope! The amp is back on the bench once again to track down a pesky noise issue. But frankly, I'm glad, because I ended up spotting a couple opportunities to improve the amp anyway. In this video, we'll track down the source "frying bacon" noise issue and I'll detail another easy mod that improves upon my previous design.

That's a nice mod on that Bassman. Do you have a price list somewhere?
It's in my head. And it goes something like this:
Fender: standard charge
Gibson: standard charge
Ampeg: standard charge
Marshall: slight upcharge if it's a DSL or TSL
Mesa Boogie: i'll disassemble it for FREE!
@@TheGuitologist What about Vox?
@@TheGuitologist I have a Double Rectifier I need upgraded.
@@TheGuitologist so no more mesas hehehe after that nightmare I'm totally agree with you
@@drdrums1 well it's basically standard charge for simple amps, ones that don't have like complicated PCB layouts and stuff, most vox's would fall into that category. I think...
As someone who was friends with Ken Fischer since 1988, I can say with certainly that Ken would have been very impressed with you, Brad. He was one of a kind. Sure miss him.
You made me smile. Thanks for that.
@@TheGuitologist Sure thing, Brad. Hope all is well.
Ken Fischer Jesus Christ. Well just about the same. 🤘
Brad! Are these heads 4ohm? Those are the old fender m-80 cabinets which I love! Not sure which input you had it in but 8ohm won't hurt will it?
That's awesome!! I thought that and I don't know both personally 😂
Glad to see and HEAR you are back Brad!!! A most amazing repair you have done😊
Hey, Brad! You played some nice licks, good stuff! The feedback sounds awesome!
I love watching you work your magic. Amazing stuff! I've learned a lot of trouble shooting tactics thanks to you man. Amazing playing!
I really enjoy your videos. I’ve been working on old tube radios for awhile and am starting to get into amp repair. Very informative stuff, and really like the way you edit your footage.
WOW! A well deserved jam after a tricky shakedown of one sizzling resistor. Seems that amp got even better in the end.🤘🤘🤘🤘🤘
All killer no filler! Great job dude! I had an old Bassman back on the day. That one sounds awesome! Metal!!!!
Oh hellz yeah! Brad and a Trainwreck. Been waiting for this one.
G'day, Brad! Great job on this Fender Bassman Amp! "It's as loud as any Marshall!!" Enjoyed the Video! Thank you!
Cheers! 😊✌🏼🎸❤️
Had one of these heads back in late 90s, shoulda had it done like this.....sounds awesome.
Lovely sounding amp. You did the right thing! Thanks for sharing your knowledge.
That’s a great sounding amp dude! Some nice chops there!
Wow man that DOES sound good! This was a great learning video for tracing problems. Even if I didn’t completely understand why you made certain changes yet. Thanx!
WOW! What a monster when all's said and done. Nice work, Brad!
Brad shreds. looks good sounds great! i see you got in the zone...Nice jam!
beautiful harmonic feedback is what love about these amps ! Nice work!!
Great vid and great job on the amp, it sounded amazing at the end, also due to your fine playing my friend : )
I contemplating buying one... Played one about three weeks ago, just incredible tone, sustain and feedback for days... Really dig it
I love how you use a marshall head as a stool man!! Great video as always!
@West Coast Cartoon what has that got to do with a great amp video buddy? Aggression can be passive as well as active and never looks good on anyone.
I'm surprised that I didn't catch this when you first put it out, Brad; glad it showed up in my feed on the rebound. Another awesome job...
Woah! Sounds monster! You have some pretty good shred chops too, man.
PRS Brad the guitologist signature series. To be release in 2021. Dont delay, request today 👍
Dude this might be the best tone in the world! I love tge trainwreck Liverpool and this might be better! Pete thorn has a fantastic trainwreck demo !
Hiya, nice amp and interesting repair.Very informative, and what a nice beast of an amp..Great test afterwards, nice playing..! Thanks for sharing, and more knowledge gained....Ed..U.K..😀
Thanks for the diagnostic video. My skill set with soldering iron is confined to pickups, capicitors and push pull pots. I would never trust myself to tinker with the power amp. Too many shocks from an old Ampeg amp from the early 1970's to remind me of the potential.
Kudos for fantastic effort. As usual.
Great noodling Brad!!! You have a really interesting and special personal repertoire that is unique and melodious. I hope you can arrange to record songs with people associated with your channel and the work you do in the very near future. I think it would be very uplifting for YOU as well ! We all need good in our lives, and the reminder that we are good. BRAD LINZY & KENTUCKY QUARANTINE would be a great name.
Great job as usual Brad!
Some smoking hot playing there at the end man! Woooooooo! 😊🤟🏽 I enjoyed that. Thanks for another awesome video Brad. Have an amazing day!
Oh man that amp ROCKS! You totally busted the ass in that annoying noise problem didn'tcha!
One GREAT amp Brad well done!
I subscribed to this channel because of you calling out rick beato (which was fun). But watching that I didn't expect these kind of videos. Very cool!
I love the tone, reminds me of 70's Santana. Great vid
Brad The Solderist - Fastest heat pencil in the East ! Appreciate the sped up soldering job - we get to see all the work in a quarter of the time - excellent !
Awesome playing man!
You do great work.
Thanks for sharing.
I have a 1967 Bassman that has the original glass with it and it's an amazing sounding amp. It's a life time piece for sure.
Brad buddy you were about too catch that guitar neck on fire lol always enjoy watching the show God bless!
Good Knight !! That thing is a Tone Mach.
Awesome looking Amp 🤟🤠🤟🔊🔊🔊🔊Great work Brad 🤟🎸🎸🎵
Perseverance paid off! Good work
Amazing guitar playing bro, keep the spirit up.
Holydamn, Brad you kick ass on that guitar! And on repairing amps! And on speaking truth. I love this channel
DUDE IT SOUNDS FREAKING AWESOME!!! THANKS FOR THE LESSON TOO!!!
Good job dude sounds rad af!!!
Brilliant, from start to finish.
nice to see some amp repair vids again. i missed it man!
Jeez Brad that's pretty wicked sounding... it's not a Fender anymore though it's some kind of bumper or bush bar now I think lol great video
Jesus Christ that amp sounds amazing...
Great job on rescuing the video with the voice over instead after the audio failed, too
That sounded awesome at the end brad !! :)
Cool high gain tone there at the end! That "Trainwreck" in the amp title would look pretty cool on an amp... some sort of nasty rock machine or something
@@VincentVader I did immediately after making the comment and was quite surprised, cool amps
lol.. Fender Trainwreck would be more like it... sounds unbelievably awesome...
11:48 I love how you're working on this thing at 3:24am. I tend to do this too from time to time. The house is nice and quiet.
Beautiful sounding amp
wow,you can really tear shit up and i mean that in a positive light.your playing is otherworldly and could easily send some "Nashville stars" packing along with most of the hard rock guys in L.A as well.you have some otherworldly chops,i dont know if you are aware of this FACT but man,you can play.im awed and ive been at it for 35+ years.i can play but you can make jaws hit the floor
Great playing!!!
Holy crap that thing is a BEAST!!
I’m steady checking my local GC dumpster! Nothing yet . But you never know
kool , I'm confident that you'll be able to get my old Musicman working again .....A ray of sunlight , on an otherwise cloudy day .....She's in overall good condition , 2 owner....only cons are...non-original speaker , purple velvet grill cloth & missing the small HD112 placard on the front....but does still have the larger Musicman placard , top corner front......As I've said , I owned 'er for over 30yrs , and it was always a great little gem amp...I'm going to miss it....truth be told , my house is just so small , that I have nowhere to keep it....especially when I get my new one.....So anyway , I'll hope to get back w/ ya after the holidays.....Hope you have a happy Holidays there...Rock onnnn , soundin' kick ass on that test out
Robert
Brad, that was some nice playing at the end.
Another AWESOME job brother!!!!
Nice fix, nice chops!
Love the intro. Great BBC comedy memories.
Keep em coming Brad!
It was Thames, an ITV franchise
Wow....always love your playing
killer! great job and video.
Sounds excellent!!
Nice work Brad!
I remember I built a Blackface Deluxe Reverb and when I finished I had some noise and squeal when the amp was turned up. I tried lots of things...in particular I cleaned up my grounds and some of my wire routing and length and couldn't find it. I changed out a few items that I though would cure it, but had many hours of trouble shooting and couldn't figure it out. I ended up buying an Oscilloscope. I checked the signal at the output and could see the wave form get these weird spikes, (that I guessed was parasitic oscillation). I ended up looking at the wave stage to stage. 1st stage was fine - second stage was fine, etc. I forget the exact spot but it was somewhere after the second stage and it was right near around the trem circuit. Turns out I had scrounged up one resistor from my box of parts that came from an unknown source, but was my only one of that value I think it was the 4.7M resistor coming off the reverb feeding the grid of the next stage. Yanked that resistor and put in a new one and bingo! That was my first experience with a signal generator and an oscilloscope. Great vids! Keep up the good work!
I really enjoy your vids.
Great video. Love a BassMan.
This is why I came to this channel awesome!
Killer video, Brad. Thanks
Haha, sitting on Marshall. Marshall really do everything :)
It's for the vibe.
Congratulations on restoring the ship of Theseus.
Had a 68 Bassman a few years back and it was pretty awesome.
sounds really nice! Many times have good players dispelled the myth that silver panel Fenders suck. Well done.
WOW! BEAUTIFUL TONES AND GUITAR PLAYING! YESSSSSSSS!!!!!!
I liked this more streamlined type of video with overdubs. More to the point! Not that I don't like your normal commentary, i like all your troubleshooting videos!
That kicks rhinobutt. What an amp! Fantastic tube tone.
You sound great and the amp, too, was well worth fixing!
Sounds killer !
That's the meanest sounding Bassman head I've ever heard. Dang. You're a killer guitarist, man. You should call yourself the Shredding Guitologist, lol.
Shredologist.
Great idea but, All the Shredding's are trademarked or being used by a TH-camr or email name. That's why I spell my name with 1D.
God what a beautiful tone
When all else fails read the schematics.
Then we wouldn't have a trainwreck to watch...once again. "We're Gonna Need Another Timmy" 😂
Cool Brad, glad you found it, I'll bet it was starting to drive you nuts, take it easy Man, :)
great vid. love baseman's!!!
I had that exact year and model played it through a ampeg cabinet with 2 15's, wish I still had it play a Precision bass through it. My first bass amp.
My two most used tools: chopstick and hemostats. Sometimes the board will become conductive after being exposed to moisture.
Luthier Vandros Yep! I’ve run into that too. Enough moisture and the fiber board will begin to conduct.
Yah if there are strange noises and all the components check out, I’ll run the meter over the board to the lugs and see what it’ll pick up. You can take a hair dryer to the board and it’ll work to remove moisture sometimes.
@@luthiervandros - alcohol will dry it and clean up any gunk too 👍
I used a Walnut dowel sharpened at one end. It's longer for those hard-to-reach Mesa boogie amps.🤘
20:10 you could go out for a bite and you'll still be hearing that one! You're a really good guitar player, Brad - even after I remember to switch off 1.5x speed :P
Sounds great
Not sure what Fender was thinking with the ab165.... I mean, I do get it. Stiffer and cleaner was the phrase of the day with all of the silver face amps, but simply taking out all of the local feedback loops makes such a huge difference.
Really fantastic sounding amp. Outstanding playing also.😏
Silverface fenders are finally getting their due, funny when I see people who used to turn their noses up at these now saying how much better they are than what's being made these days
Sir, great tone, great Bassman tone. Really sounds very Joe Perry, Brad Whitford tone, like that, rich, thick and bright. My Bassman use includes the front channel with the 'deep' switch toggled, then ganged to the second channel for more 'adjustment.' Really like the 'deep' switch, careful with that solder gun,,,,,thanks,
Brad, you're fuk'n wicked smart when it comes to amplifiers, dude !!!
this thing sounds insane
Bloody good guitarist!!!
Well Done!!!
I enjoy these very informative videos and I always learn useful things.
Brad and Uncle Doug are great resources AND are very entertaining 👍🍻
Except Uncle's playing sux bigtime. Pets and hotrods compensate for this. a bit.
Uncle Doug is far and away superior in electronics knowledge and the ability to teach it , but Brad has come a long way from his first muddling around in an amp. Brad IS a very excellent guitarist ...
@@jenniferwhitewolf3784 I couldn't agree more. But Uncle Doug's playing still sucks as bad as Brad's politics. (I know, one should never say so). They both aim for the same amplifier characteristics, and I sure appreciate that. I look forward equally to posts from both of them.
I trained as a mechanical aerospace engineer in the 60's, and made guitars and amplifiers for our 5-man rock band when we couldn't buy them. We created 50W amps using EL34s and heavy duty twin-cone 12s in twin bass reflex enclosures, so Brad and Doug bring back many pleasant memories.
@@jenniferwhitewolf3784 Yes, Brad can play well.
@@tonyduncan9852 Interesting information Mr. Tony 👍. I spent a couple of years around aircraft in the early 80's. Sweeping floors and taking out the trash from the hangar.
I got to change the oil on our Piper Aerostar a few times.
Darn….again wish you were local I got the same silver face, stock fenders are just too tame, even my restored Blackface, awesome!
Aesthetically speaking, was never big on PRS guitars. But that red one is gorgeous. Like the old BÖC song, "...red & black, that's our color scheme". Yeah - hard to eff up with a red guitar, regardless of brand.
Btw, that amp sounds killer & that's thru my phone. Can only imagine what it's like being in the same room with it & a good cab.
The bacon 🥓 was making me hungry in the beginning of the video but I found myself reaching for my drum sticks in the finale.
