So I decided to start simple on my first project and build a guitar pedal out of a voice changer toy i've had for a while. I opened it up and it had in/out leads, went online and found a basic true bypass circuit and wired it up. The schematic I used is here - http://www.flickr.com/photos/39729358@N00/2239032639
Unfortunately, a clean guitar signal going into the effected channel is too weak for some reason....seems to be some sort of gate in the circuit. If I plug in a powered source I can dial it in so that I get smooth volume transition between clean and effected, but an electric guitar on its own just doesnt cut it.
I want to remedy this by boosting the signal in the effect chain- IE AFTER it goes through the DPDT switch but BEFORE it hits the toy. I tried doing this with a little radioshack test amplifier, but all i got was terrible deathly screaming noises with no indication of the original guitar signal. I probably wired it wrong and it looped back onto itself or something crazy like that. So basically, I have a simple +/- in and +/- out from that little amp that I want to insert into that specific spot in the pedal circuit. Can anybody help me do this? I'd be so grateful, and this would mean my first successful build.
