Anyone know what the Marshall JackHammer is schematic-wise - anyone have a schematic? It looks like it may be a TS clone (or clone of the Boss HM-2). It has a OD/Dist selector which if I were to guess switches between either soft clipping/hard clipping, i.e. diodes and LEDs for the clipping section? I ask all this as a friend just obtained one of these and used it in front of a Carvin Vintage tube amp and the clarity of the overdrive was very nice, could distinguish all notes in a chord played while it had sweet singing sustain for solos. Impressive pedal actually. Anyone have any info about this pedal, a schematic to make one, what the MadBean equivalent may be? Anyone? Anyone?

Thanks for the schematic. So.... can anyone explain it? :o I am not the sharpest tool in the pedal builder workshop! It looks like it uses 3 TL072 ICs, is that correct? So with 3 ICs this isn't exaclty a TS clone? It also appears my guess is right that the OD/DIST toggles between LEDs and diodes for the clipping section.
Sounds like you have a basic understanding of it.
I had this pedal for a long time. You can find them used for less than $50, it's not really worth building I don't think.
The plexitone is where it's at for the same sort of tone.
