Hi there. I've just (about) finished a fuzz pedal build but have had some problems and am trying to debug. The pedal I built is based off the Axis Face Silicon Schematics. While the signal goes through when in standby, there is no sound once it is switched to the circuit. The led is going on ok, but the weird thing is that I accidentally discovered that if I touch the tips of the out put and input together I get fuzz!! I have been staring at it for hours but can't understand what I have done wrong or why directly connecting the input and output seems to get the circuit working????
Here's how the 3PDT switch is wired.
123
456
789
1: input to circuit
2: output from circuit
3: +9v for led
4: input from guitar
5: output to amp
6: 1k resistor to led to ground
7 and 8 are tied together and 9 is empty
Again.. the only way to get the fuzz to sound is to jumper 4 and 5.. but I don't see why this works or if it is safe to just jumper them. It makes it seem as the the circuit input and output are the wrong way around, but I'm am certain they are not.
If any gurus have any ideas that a noob like me could miss, I would greatly appreciate it. Thanks for reading all this.
