Loud Squeal

Post by mdm002 »

I took out my jj 84's to try and see if these sovteks I had around were better matched and they weren't. When I put the jj's back in and turned it on the amp squeals really loud. I replaced tubes again and the same thing happened. Does anyone know what would make the amp squeal even with the gain all the way down? I pulled the first pre tube in normal channel and it still did it. Any suggestions?

Tremolo foot switch squeal!

Post by mdm002 »

I realized that when I changed tubes, I also pulled out my tremolo foot switch. So when I plug in the switch it doesn't squeal even when i switch it either way. Once I unplug it it squeals. I am not using the switch in the jack, so that when there is no foot switch it should be tremolo on. If the tip doesn't short to ground when there is no foot switch because I did not use the switch how can this be different then when the switch is plugged in and is open?
