The DigiTech XMM Metal Master Heavy Metal Distortion Pedal makes any amp sound raging. Multidistortion technology produces seemingly endless distortion types that can be morphed into wild combinations. Morph among endless combinations of the most brain shredding, headbangin' distortions out there: the Boogie Mark III, Boss Metal Zone, DOD Death Metal, Rectifier, and beyond! The Metal Master also features powerful spectral-contouring EQ plus a clean signal out and a special out for cab modeling. High enough quality for studio use. Distortion pedal controls include Level, Lo and Hi EQs, and Morph.
