A heavy weight (in every sense of the word!) Initially, I was looking for a 210 able to withstand my head SVT 3 Pro, so there no worries, eligible 400W 8ohms are there! For cons, I find it difficult to use alone, it does wonders in addition to the 15 'tandem and works remarkably well.
We do not buy the Mesa for its neutrality. This is typed (especially with a Ampeg head!) Sound like or do not like. The sound is clear, very responsive, no bottoming, even at high volume.
I use it recently, but does not regret the purchase, even if the problem of the weight of the beast is definitely there when you have the handle!
Advantage: the fly version I have is indestructible
