I played a sweet matchless today, had it krankin, playing some blues at guitar center (more about that experience later
) anyway, i went to turn it down, and the master is about at 4, and i hit the master... and its a push pull knob... and it was out, i hit it in and BOOM the amp went into a huge feedback loop and was amazingly loud.... It scared the **** outa me.... I was totally gonna buy it... but then I looked at the price tag... 4000 dollars USED!!@!##!@!
