Through trying different Amplifiers and different Distortion pedals , I've found the best tone for styles like Metallic, Pantera and Slayer through this pedal , the Gain is unbelievable , if you have a guitar equipped with EMG's or any sort of Active Humbuckers then you should definitely try this out .Ive been trying to replicate the tone on Metallicas Master Of Puppets for years and i was able to get this very close with the EQ control , Also able to get a very nice Pantera-esque tone from this pedal , if you play any type of metal i firmly believe this pedal will settle your differences , A very good choice and im very happy with it , used in bedroom , studio and live gigs , i have tried and tested and it has never failed me once , right out the box it sounded bad to the bone , Heavily recommended guys !
