I've had one of these for a few years now and no real complaints . . . except . . . I've noticed recently that it does not seem to be producing the same volume that I recall when it was new. Sound quality still good (does not sound like a blown speaker). I take good care if it (keep it covered when not in use - don't leave it in the car, etc.) I've played it a good bit - 2-3 times a week, 3-4 hours per gig over the 3+ years I've had it. I plan on getting it looked at, but just wanted to run this out there and see if anyone had a similar problem and what was the fix. I know this was Ampeg's first take w/ the on-board digital effects - not sure if there were some problems. Any insight would be appreciated.
