Hey all i have a problem. Alright when I'm using my amp on my brown channel with little to no gain (using as a clean) there is no hum or feedback, but when i use the Ultra channel (gain midway) there is a lot of hum. AND! I'm using an ISP decimator through the input not the effects. If i use it through the effects loop there is squealing feed back. I'm assuming the cause is 60 cycle hum but I'm not sure. Anyone care to help?

its probably some of the effects. try putting the decimator at the end of your fx loop, and adjust the settings on your pedals so that you dont get feed back. I have the same thing, but not as bad.

But i know it's not my pedals cause that was the only thing running. It's the amp itself, it's a very loud hum even on standby.

it's the 60-cycle. is this playing through your jem?

i may be wrong, but if you have one of those huge 30-slider EQs, you might can turn that frequency all the way down, amirite?


also- the decimater is a noise gate right? noise gates are supposed to go in front of the amp, only in the effects loop if there are several effects in the loop causing hum.

edit- have you checked your cable?

before dropping any money. try it at different power outlets, or even better, at a different place to see if it isnt just that outlet or something.


wait a minute, you said you checked your cable, i meant using a completely different cable. i dont think a multimeter shows hum
