Hey folks, I had a gig on Friday night at a bar that is shall we say, not the nicest place we play... old, beat up and showing signs of having been worked hard and put away wet for a number of years. So, we get ourselves set up, I have my Marshall VBA400 on stand by for a few minutes then engage the amp in order to do a brief sound check. (Cab is a NV610) As soon as I bring the amp up to performance level, I noticed that I was getting an audible distortion on the attack of the note, but only on the actual attack. It was not there after initial transient of the note diminished. I tried to replicate the problem here at home and have not been able to do so, even after an hour of running the amp pretty darn loud. (I know my neighbours were wondering why their stuff was sliding across the room!) So, my question again, does this "symptom" sound like it could be bad power at the club? No, as of right now, I don't have a power conditioner... responses here may well have me shopping for one though! Many thanks, Fishheadjoe *** bass used was a Pedulla Rapture with a fresh battery, so I assume that wasn't it and again, I couldn't replicate the problem at home!
