Looking for JHS Bomb Boost Schematics

[dinkyguitar]

Hi All,

I'm looking to build a guitar boost pedal and found instructions for the JHS Bomb Boost (not the mini one) but I can't find the schematics.

Anyone know where I can find these schematics....or better yet a similar or better pedal I can build?

Google Tim Escobedo’s Duende boost circuit, that’s where JHS poached it from

You could pretty much do a vero from those pictures

I thought about tracing the circuit from the pic's but I'm not sure if it I can get it 100% right...

Fuzzdog has a board for it with schematic. http://pedalparts.co.uk/docs/DudeBoost.pdf

The stewmac/JHS board has a few extra resistors (1k, 47r) that aren’t necessary (they’re for power filtering and switch noise). Also the 5k1 resistor is replaced with a trimmer as JHS definitely cherry picked J201s for it.
