Why some people's using these little magic blue pills... playing a MarkIV is safer and give exactly the same results :lol: :lol: :lol:
Seriously, this amp is a tone monster, i just came back home after my Saturday nigth club concert, and the MarkIV have given to me all the tones i've needed which have inspired me so much... what i have to say , this amp is the better amp i've ever played !!!
