This is kind of a funny thing to post in a Mesa oriented thread. If you feel this way, why do you continue to own Mesa gear ?
I was unaware that Mesa had a significant quality issue with any of their recent bass amps (Titan, M9). Even here on TB, where the focus on bad unit quality, and poor CS is laser sharp, all I can recall is a few folks having some bad experiences, which can/will happen with any manufactured item. OTOH, it seems the more common experience is that Mesa build quality is quite high, their CS reputation is pretty stellar, and they back their gear with such strong warranties, it's hard to imagine them putting out many bad units of anything.
as to your personal opinion on the value of Mesa gear for the money - I'm guessing you won't get much traction in this thread on that position.
FWIW, I have a 5 year old WA 12 that has been gigged hard, I and have never experienced an issue with it. Also have owned a Venture 2x12, a Buster head, a Scout 1x12 ext cab and a Scout 1x15 ext cab - none of which exhibited anything but great performance. I also never felt that I did not get great value for the money I paid for all that Mesa gear.
