I purchased a new Markbass CMD 102P a month ago, and have played it about an hour a day. When I first purchased it, it sounded great at low volumes, up to about 30% master volume. It now sounds good up to about 50%-60% of master volume. I played their 121 combo the other day at GC and it was killer up to at least 50% (I didn't try any louder). It seems like it is headed in the right direction, but has anyone else taken awhile to break this stuff in? I've only bought used gear in the past (but got a super deal on this), so is this maybe just a normal break in period for the cab?
