Hey everyone!
I got this fuzz/dirt pedal off of eBay sometime ago which the seller had dubbed "The Dirty Harry". I getting ready to wire up a board using a power supply with isolated outputs but I'm still definitely gonna have to daisy chain at least one of the slots... I'm trying to get all of the milliamp values for my pedals but I have no clue what this circuit is and no voltage meter thingamajigger. Also, the circuit board doesn't have any name or company name on it unfortunately...
Check out the picture on my IG if ya don't mind and see if this riddle can be solved!

The trannies are 2N5088's and there's 3 of them.
I appreciate any help or any points in the right direction!
Tye

I need to see the other side to trace it. also need the resistor color codes if you can. I am not sure if the colors I see are correct. the 4n7 caps are kemet, the other box caps look like they are from mammoth electronics and the resistors are metal film. google metal film resistor color codes.

Looks like a GuitarPCB.com board.

Looks like the American Fuzz Pro - the fuzz of choice for professional fuzz users in the USA, damn I wish I wasn't stuck with all my amateur fuzzes.


Some kind of Fuzzrite with a 3rd transistor it seems.

Direct measure the current draw for best results, probably largely inconsequential.
