First off: A big thanks for the help.  I really had no idea where to start.

Alright: I will look into the potentiometers on the amp. Some of the posts made this the starting point. It has been well traveled around the country and not in the best conditions. If that stuff is flimsy, it probably wriggled itself out. I have access to a multimeter and can check things for resistance and capacitance.

You are right on both assumptions: I do not deal with guitar amp electronics or electronic workings. Oddly enough, I rebuilt a Squire a few years back with limited knowledge. I am probably lucky I have not electrocuted myself. That said, I will be careful. I know electricity can be stored but I though caps dissipated with time. I appreciate the heads up.

So I will go get it and see what I can do. Like I said, the amp is decent for me and I don't want to toss it out if it is a small problem.

Again, thank you.

Hello from your forum noob. I was glad to find this forum from my searching efforts.

Anywho, I have a couple of quick directional questions. So if these are covered elsewhere, please forgive a forum noob.

1. I have a Crate GX30M that crackles intermitently. My main guitar is a Ibanez RG series. The crackle happens on the clean channel.  I have the reverb on but on 3 or 4.  I think I bought it in 1990 or 1991. I know the amp is not worth much but I would like to see if I can repair it before I invest in another amp. Where should I start?

2. Is this book: The Complete Guide to Guitar and Amp Maintenance: A Practical Manual for Every Guitar Player any good for troubleshooting? Would any of you reccomend one that is better?

Thanks in advance!
