Please remember to always turn the fan on; at least when mounting this beast to a rack.
All issues I had with my Mesa400 came from overheating.
Broken capacitors and everything...
I play it through Mesa 2-12 and 2-10 cabs with no effects or anything and get regular compliments for my tone from FOH and fellow musicians. (And I'm not the best player, by the way...)
This is how a bass should sound like. Go and shoot one on Ebay!
