If I remember right these pedals were used on Carcass' Heartwork. Now of course that album has incredible sound but is the pedal worth spending money on? I have an Maxon OD808 and Boss HM-2 (for the really dirty stuff), would the Guv'nor provide me with something extra? Does any one here have any experience with this pedal and possibly the differences between the original and the newer Guv'nor IIplus version? Any replies would be helpful
