It's Great, but...
Before i carry on, I want everyone to know that this amp is badass! If you're a hard rock\metal guitarist and you're looking for an amp that fills in the mids and bass very well, and not to mention a nicely voiced clean channel, i say go for this. That being said however, I think i got one that may have been defective. When you plug in a tube amp, the lights behind the grill\face of the amp are supposed to come on (the lights tend to be coloured, mainly for aesthetic) However my amps lights would flicker and fade out slowly along with the sound from the overdrive channel. The weirdest thing is that the clean channel is un affected, and the tubes have been changed. The overdrive channel doesn't work anymore, but i still use it by throwing an overdive pedal on the clean channel. It really is a great amp. I just have bad luck iguess ;P
This is my Main Amp
Brutal, clear and punchy. It's everything you need, if you want to get a tight death metal sound. It's used on our new album Exorcism.
