silentbob Posted October 26, 2010 Share Posted October 26, 2010 Getting a funny background noise from my amp this evening. It sort of sounds like the hissy crackle you get when you turn a dodgy pot, but i'm not turning anything. It's just there when i play, but not when i stop playing. The amp is a Crate BT100, and it's only had home use while in my ownership, never been turned up over halfway. Any ideas where i should start looking?

geoffbyrne Posted October 27, 2010 Share Posted October 27, 2010 If there's an FX loop on it, take a jack plug & put it in & out of both the sockets, say, 20 times - also do the same if there's a headphone socket. I've also found that the phono connectors going into a reverb tank (if you have one) can cause this. Otherwise it could be a dry solder joint or a cap going dry. G.

flyfisher Posted October 27, 2010 Share Posted October 27, 2010 All the above, plus turn all the pots end-to-end a few times. Quote Link to comment Share on other sites More sharing options...
silentbob Posted October 27, 2010 Author Share Posted October 27, 2010 Just turned the amp on to try out some of these fixes, and the noise has gone. At least i have some stuff to try if it comes back again. Thanks guys. Quote Link to comment Share on other sites More sharing options...
