The pedal i am building is a microamp, sho, and ehx hog's foot.
i've got the SHO working without much trouble.
But the microamp and the Hog's foot both suffer the same problem. they have a quiet buzzy distortion, like a really bad square wave fuzz not even up to unity when the pots are on full.
tested the Hog's foot transistor and it seems like i finally got it the right way round because its making SOME noise now, also tested using the voltmeter at c+e and shorting b+c, b+e and all was fine. there were contradicting sources on the orientation of the 2n3904.
the voltages on the IC also seem to be reasonable for the Microamp. been through every debugging article, through every connection and I can't work it out. Do these things need some external biasing procedure?
(having said that, PIN 3 is actually too low.... they are in order: 0,~4, 0.3, 0, 0, 4, 8, 0
Triple booster woes:
ok got the microamp working. wrong value resistor.
still nothing on the hog's foot. I'm thinking transistor-would it make this sound if it was the transistor at fault, either wired backwards or fried?
a 2n3904 would be, flat side facing, pins down, left to right: 1-emitter, 2-base, 3-collector is this right?
