I just bought an Orange Rockerverb 30 combo, which is an awesome (and expensive) little amp. When I played through it at home I noticed a consistent loud hum coming from the amp. I play a Schecter with Seymour Duncans and strongly dont believe it's my guitar. That and I've played the same guitar through three different amps (Peavey Classic 50, Blues Jr., Vetta) in the house and never had such a noise problem. When I cut the guitar volume off while the amps plugged up and the amps on, there is very little noise. I turn up my guitar volume (on either pup) and it's instant buzzkill- loud buzzing and humming. I move away from the amp, no difference. I turn it on clean channel, a little better but not by much... You guys got anything?
