Hi,
I wanted to share the guts of this pedal that I will have for a few days.

I will upload the photos in a google + album, do not hesitate to ask me for more photos or values.

Greetings

Values would be great; a trace would be better. :wink:

I'm guessing a modded Marshall Guv'nor?

There is the value of the resistors and the electrolytic capacitors. Unfortunately I do not have an SMD tester to measure the capacitors.

I will try to get one

HMMM
In Marshall's no equalizer with operational amplifier
There is an operational amplifier
Does anyone know what scheme is used here?
I know that JHS "Loves" Madbean and AMZ but the three-band equalizer circuits have no

Hello, Im thinking about this version of angry charlie, alot. I was thinking that was a Guv 'nor modded. but the guv 'nor its very weak close to this pedal. now with this other op amp on the game. Im sure that's not like a guv'nor. maybe an shred master. really dont now. :oops:

I was looking on the pots. and theres bass B25k, mid B25k, treble B100k. on guv'nor its all 10k. on shred master bass B100k treble B25k(Contour B100k in other section). maybe its something around the shred master. but without the contour section. and 3EQ stacking together

Thanks, but that is a useless effort. CB has nothing to do here. :thumbsup
With all respect, the hard work is done so if you want to help, put your eyes on those pictures, compare with the originals and find/add something new :hug:
