WattGrinder is now specializing in guitar cabs loaded with 15" Eminence guitar speakers. The idea is to give players more body and dynamic range a la SRV in the ’80s. The cabs are also aimed at 7- and 8-string guitarists who have a larger frequency range. WattGrinder also builds cabs with 12" speakers, and incorporates a Dominator-style split-angle that is aimed to spread sound around a space in a big way.
