Sound — 6
I have a prettey crappy guitar but the pickup in the neck is very hot and distortioney. Not really enough gain but a lot of sustain. Also the turbo means I get another type of distortion which is a totally different tone and slightly louder then the first mode. Also you can switch between modes with a footswitch. which is nice! The tone though was no where near as good as my amp which is tube powered.
Overall Impression — 8
I play stuff like rock, metal and Grunge and it works quite well, especially if your one of those destructive "let's axe my axe" types although if you did use it in a concert it would stop before the end without a 20 adaptor (actually I paid 10 for mine). I'm really a begginer so I'm not that good yet. If you do want to get one of these, I think you should get an overdrive/distrtion pedal or somtheng else.
