Hi,

I have been having problems with an intermittant hum and sometimes buzzing on my Line 6 Spider Classic 15, which was bought new, but is out of warrentee. So far, I have tried several different good quality cables, had my guitar serviced/set up, tried different electic outlets, and even took the amp to Guitar Center where they were unable to dublicate the buzzing. The noise is less noticible at times, but I have been unable to correlate it with any variables on my end. Guitar Center recommended going to a local amp guy, but that cost threee times more than the amp cost. Does this amp need to be retired at one year old, or am I missing something?

Thank you!

Rob
