I have a chance to get either a mesa boogie mpulse600 or basis m2000 at good prices. ive read about some reliability issues with the m2000, anybody know how believable this complaints are. i play rock and like the sound of Mesas but i can't decide between these two. I think the M2000 would be alot of fun to play through but i dont want an unreliable amp, if i buy something i cant be worrying about it. please help me out if you can also the m2000 will have 4 years left on the warranty if that makes a difference in opinion.
