I plug the guitar in, hook up the speaker, and power it on, and all I get is a buzz. The speaker pops when plugged in, and also when the pickup selection switch (stratocaster) is used. I'm wondering what it might be. It all appears to be wired up the way the diagram shows. What might this be caused by? And just in case anyone was curious, no, I can't get the guitar to give any noise on the noisy cricket, but it works in other amps. Also, the grit switch seems to increase the gain the way it should, so I think the lm386 is working properly.
