UTILIZATION

plain

SOUND QUALITY

sounds great plugged into my classic 30

The clean channel is quite insignificant
the crunch is great, and the gain is therefore
the distortion is very good, with good headroom
With good microphones, you can easily play metallica metal genre (probably not enough, however, saturated to the death or slipknot)

ISF is a fucking invention

OVERALL OPINION

to buy ...
