Here's my review of the Overdriver from Vick Audio. Based on the classic Colorsound Powerboost and Overdriver this one's got a super transparent tone, with crisp top end, thunderous lows and lots of tube-like gain on tap. I'm using a Fender Strat with D Allen Voodoo 69 neck and middle pickups and a Seymour Duncan SSL5 bridge pickup into a Reeves Custom 50, with a TRex Replica for delays.
