Hello to all

I bought a jvm 410 h last december along with a 1960a cabinet. It has worked fine until recently it seems that the clean channel is really dirty, especially with i hit hard notes. There is a lot of popping coming from the amp too. Is this a problem with the tubes? or could it be a cable or something? Please help..

Thanks

It might be a tube problem.

Sounds like a tube problem. If this is on Clean Green Mode, the its definitly a problem. I know the first runs of the amp had some bad tubes. Mine did.

Take it to a tech. You paid to much for it to not get it looked at. : )
