I need to know what caps resistors or whatsoever needed to mod my mark IIII blue STRIPE to the III++.
Thank you all and appreciated.

the amp still has the grainy character of the Mark III. As I said in that thread, keeping the pull shift disengaged gives a considerably closer sound to a IIC+. I can't see any component values in the pull shift circuit that differ between the III and the IIC+ however there must be a reason for this difference, I've heard it in other demos of Mike B-done Mark III+ amps, or I'd be tempted to put it down to my use of metal film rather than carbon film or carbon comp resistors. It may be that the component differences shown in the above IIC+ schematics are responsible, but I'm also sceptical about that.

C26 is apparently something to do with the 5 band EQ
Is this mod related to this one done by this guy?
Much obliged!!!jrb32 said:No problem! For reference this is the amount of work required for to do a full III to IIC+ conversion on a Black Stripe! I see why Mesa don't offer this. I might also permanently wire in R105 and C47 to ground and remove R126 to see what happens!
Thanks and good luck! Definitely recommend the easier version listed about. Plus these are for a Black Stripe so for a Blue you'd need to trace and double check everything first. Just do the easy mod

Jon I've got a few questions about some parts I'll fire at you soon. I think r126 was one of them
"I don't think the grainyness is a fault. What it sounds like to me is the way it affects the voicing of the gain structure pre-distortion. Treble shift lets more low end/low mids through. When I have it activated I get great saturation but there's a low mid kind of sound that the IIC+ doesn't have and the III doesn't have with it not pulled. It translates as less tightness and attack."
