I was wondering if somebody could help me with this..
I just built:
broken link removed
And put it on the inside of a guitar (removed 2 of the pickups in a fender strat and put it there)
I checked it over a million times and it is exactly as it is on the schematic, except for the ground from the battery does not go to the input plug but just goes to the ground of the circuit (since it is not hooked up using a plug from the amp or guitar but hooked directly up to a DPDT switch). I also connected a 1 nF ceramic cap from the 22 uF cap to the emitter of Q2 because I saw that in a similiar schematic of this circuit and thought it might help.
When i turn the "level" all the way up and start turning the "fuzz" up...
There is a very very High pitched squeeling and as you keep turning it up it turns into a very very low squeeling (Kind of like a sound effects of a bomb dropping then exploding).
When I pluck any strings i get sound behind the squelching, but it is pretty much just deeper then the clean version and doesnt sound anything like a fuzz.
However, when I turn the "level" slightly down, I am able to turn the fuzz up with very little squelching, but there is no fuzz.
I had a few theories about this but I am not sure what it is...
1. Could it be from the magnetic field giving such bad feedback from the single pickup? (the circuit is about an inch or 2 from it).
2. Unwanted ground loops? I tried seperating everything using electrical tape but it was no use in fixing the problem.
3. The cable to connect the guitar to the amp I am using is horrible and I dont use it because it has bad feedback through it, but I left all of my other cables at school so this is all i had. Could this be a cause for such bad feedback?
Everything is very well seperated on the circuit board, and I changed everything to ceramic caps except the 100 uF and 22 uF are horizontal electrolytic.
Please any suggestions would help out alot.
