Not sure if this belongs here, setup, or effects. I have an Ibanez BTB 510, Hartke 4000, Ibanez Phat Head, Boss Chourus, and Avatar 212 and 410...I'm looking for a Tim Commerfeld type grind but just can't seem to dial it in. The amount of control that I have just seems to be daunting at times. It would seem like I would be able to dial something in but it just seems like fuzz to me. I know that Tim uses overdriven cabs...is that hte only way? What is this Ampeg grind I hear about? Anyone, anyone?
