Hello all,
Recently I bought a Zoom G1xon effects processor, and I am trying it with a homemade amp I did based on an LM386 ic. I didn't expect to work properly. What happens is that any guitar I connect to the g1xon and to the amp produced in general a lot of noise, and if I turn the volume of the guitar up, a high pitch squeal, like feedback sound starts to sound. Have you had these sort of sounds in any unwanted situation? Maybe I can get some tips to solve it. The amp by itself with just a guitar works well, with a bit of hum of course, but fine. I attach a photograph of the diy amp.
