The La Machine was one of our favorite fuzz boxes to come out of MXR, and theyve outdone themselves with the new Sub Machine, which takes the La Machines fuzz and adds a sub-octave control along with an option to run the sub-octave signal either straight into the fuzz or along side it for a super wide range of low-end fun. A great fuzz pedal for filling out the bass and giving your music some earth shaking textures.
