Hi there, some time ago i started a quite ambitious project:
To build a fuzz factory inside my guitar.
so first step, before cutting the guitar, build and test the clone, right?
so, i did that, and what i got was a distortion, with very little volume, all knobs seem to do nothing, the only knob that has any effect on the sound is the drive knob.
here's the schematic and the pcb layout:

so, what i've been thinking:
i've not found some parts, and so i had to replace them with similar parts.
i have not used 5K Linear Pots, instead i had to used 4,7K pots.
I did not use the AC 128 Ge Transistors, I used Also Ge PNP AC 188K transistors, which seem to have a way higher gain (AC128: 55-175 ; AC 188K: 100-500).
I think the problem is the gain, but with higher gain shouldnt i get higher volume instead of lower volume?
I'm not an expert on electronics, but i know enough, so use all the technical terms you need to.
Thanks in advance
