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.

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

Greetings

Great! Many thanks for your time and help.

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

JUMP
AND one more thing )))

the bottom of the board to which a resistor R201 a diode D201 and transistor Q200

nobody knows?
So sad

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.

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

I've been working a little
NOT VERIFIED YET... that Treble control ... help?

may be something like that

on your chart higher filter does not seem quite normal

I know... that's way I posted It... follow the traces and look if you can find any clue

bro what program you drew this diagram
I try to draw Charlie Brown traced scheme to test and try to help you =)

Thanks, but that is a useless effort. CB has nothing to do here.
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

I am a noob and do the first steps in this direction
It is a good mystery to me, if you can make out to be great
Thanks for the program =)

Hey everyone, no chance to know the smd caps values there?

The LM833 section is a MI Audio Crunch Box

yes

Tinking with fresh head, there's nothing uber wrong with the tone control, just need to be rearranged in the schemo to clarify... soon. Thanks POTL

How soon is soon? Now, we need to figure out some values
