Gibson Mark IIC+ squeal issue
Figured I'd test the internets theory on how this happens. I'm gonna guess all the Mark IIC+ reissues do this

Here's one minute and 30 seconds of something I was working on, with a video of the solo I grabbed. This is "16 Whole Boobs" for the band Self Titled Album. Equipment used for recording this track is a Kramer Pacer with EMGs, 1982 Mesa Mark IIB for both cleans and distortion sounds, through a Marshall 4x12 with G12M-70s, and blended with an IR of a 4x12 with creambacks. In the loop is a Line 6 ...

I challenged myself to a solo, and tried to video it. Music is a track that will be dropping under the band Self Titled Album.
Speed chugging lesson

I get asked a lot how I can chug so fast and tight. So heres a video of how, and what I learned to make it happen. Equipment used is Kramer Pacer Satchel with an EMG 85 in the bridge, and 81TW in the neck Laney VH100R 1980's Marshall 1965B 4x10 with original G10L-35 speakers

submission for Rapidlick 16, recorded it as more a backing track type setup, in Drop B in a Les Paul Standard using a Mesa Studio .22
Wow, this is wild. I've never had this issue even once with my Mark IV. However, sounds like you are enjoying the amp. I love that they reissued this.
Read the manual. Learn how to dial in your amp
This is the price of entry for sensitive controls. On modern marks, the input gain is fixed at a value below what causes the problem in this video.
Tap each preamp tube with a pencil eraser. One of them will make a ringing sound. Replace that tube. Profit.
Literally the most common issue to have with any amp. It's a microphonic tube. $15 fix. If you don't know this WHY do you own a $3600 amplifier? I think the Boss Katana is more your speed..
@@davidfaustino4476 you must be talking pre COVID inflation prices. Preamp tubes are about a little over $20 USD now. This isn't a bad pre amp tube. Mesa screen tests their tubes to a specific tolerence. Whole reason they're branded "Mesa"... Now I need to look at the schematics, as well as compare to my 1983 Mark IIB, as the Mark IIC+ was basically a modded version, of that circuit. The main thing that changed between the Mark IIB and Mark IIC, was the effects loop.
All that for 4 grand.....what a deal 😆
My mark III blue stripe circa 1988/1989 did the same thing in these similar settings. If you want an accurate reissue of an old amp design, you gotta deal with the caveats.
@themodernguitarist if that is concerned normal in the mesa boogie world then I'm glad I never owned one because that is totally unacceptable to me.
oh
This is from Mesa Boogie. The Boogie is intended to offer its full range of great sounds at any volume from soft to extremely loud. And in order to do this, the controls must be very powerful. When turning up the Masters and playing louder and louder, you should expect to reduce the settings of Lead Drive, push in the Lead Bright and possibly reduce Volume 1 or the Presence. Otherwise you push the 12AX7 preamp tubes beyond their feasible range and feedback and ringing may begin to occur. This is normal and there is usually nothing wrong. It is like having a Ferrari that handles corners great and will also go 160 on the straight...it still can't be expected to go 150 around a tight hair-pin turn! Learn to balance your sensitivity controls (Volume 1, Lead Drive, Lead Bright and Presence) with your power controls (Master, Lead Master). Having them all too high at once increases the noise and problems without improving the sound. Like the tires on the Ferrari, you will have to maintain your 12AX7 preamp tubes much more carefully if you insist on "flying around those hairpin turns" with everything wide open!
@@alexanderzaldivar2835 quite true. We also live in a world that lacks the common sense to RTFM. Even the original 2 channel Dual and Triple Rectifiers had this in the pages of the manual.
Yep.. but it's also a microphonic tube.
Microphonic tube?
@@rocketpigrecords3719let the internet believe what they wish.
@Supergrunged Gibson ragebait do be bringing in the views & comments, lol
all the preorder people should get fixed and perfect reissue mark llc+ if we continue loud and clear the SQUEEL ISSUE!
Old Marks do this. My 1988 Mark III blue stripe squeals like this if you do extreme settings like this.
I’ve found if you run the treble at 8 or higher it gets the squeal. I keep mine at 7 and it seems fine
Where is your presence level set? Turn down the presence
@@charlesrocks presence at 2.5...
@ daaaang. That’s weird.
What are your thoughts on the amp? I posted 3 videos talking about this and demonstration how my Mark III+ doesn't behave the same way with those settings.
@@paulazzi1855 I enjoy this amp more then the HRG Blue Stipe Mark III I had in the past. And it fits perfectly next to my 1983 Mark IIB HRG. I don't feel the need to return the amp due to this issue, as I don't run the amp bright enough to make it an issue. It sounds fantastic. And I'm sure a mod will come around through forums to fix the issue. Just an oversight on Gibson's part.
@@SupergrungedThis fix should come from the company. And I didn't remember you or the other guy engaging the Pull Bright. And even if it was because of Pull Bright we can't go easy on someone's mistake with the build, especially if people spent 3600, it's already quite high.
@@fedrek01 It can come out with a couple different combinations. I never use the bass shift and can run everything else pulled and high...it sounds great. However, it will squeal if I pull the bass at that point.
Does this happen at more “realistic” volumes? Or does this only occur at the volume shown?
@@earlerylander all volumes it happens.

Cool adaptation- I dig it! 🎸🔥👌
