While the tone does nothing for me I can see why Billy likes it. He is the leader of The Smashing Pumpkins. He has a lot of fuzz (fuzz pedals) in his tone. That's his tone. The amp sounds like it has a fuzz pedal circuit in it. I actually really like The Smashing Pumpkins but that guitar tone is not something I go after personally. I bet there are 19 other people out there though that do - and will buy this amp.
