I'm using Eminence v12s. Haven't tried a boost. I've never really been into boosting. I think I had the presence almost all the way off, if not off completely. I find the presence adds alot of "buzz", kinda like a recto type sound. I'm trying to get a crisp rhythm tone, with a nice bitting lead with out being ice picky. I've got gigs this weekend I was hoping to use it for. I messed around more tonight but I'm still fighting with it a bit.
