MXR M225 Sub Machine for sale. The knob controls the sub-octave, and the switch adds the upper octave. Perfect for a RATM-esque approach. <Overview> This pedal combines the La Machine fuzz, which can create a wide range of sounds from 70's hard rock to modern garage rock, with an octaver that produces a growling heavy tone. It features a SERIES switch that inputs the octaver signal into the fuzz, allowing for even more extreme sound creation. Used only at home. There are no noticeable scratches or stains. Due to the nature of the product, no returns or exchanges are accepted. #Tom Morello #Stevie Ray Vaughan #Jack White #Jimi Hendrix #doom #ドゥーム
