just got a v2. seems like it has potential but at the moment it has no balls and is super noisey even with gates on the tube od channel. with a maxon boosting it with way too much drive from the pedal the gain is barely jcm 800 ish. the amp is used but in great shape i think the tubes r old i replaced all the 12ax7's n it got a little better but no more gain on tap. i dont have a 12at7. any one with knowlegde of this think the 12at7is bad it looks old. what happens when this tube goes bad ? anything like i got going on? thanks
