Roger Mayer Axis Fuzz Effect Pedal Electronically the Axis uses a discrete circuit configuration that is completely unlike the simple and crude Fuzz Face configuration. Both PNP and NPN silicon low noise transistors are used in an unique configuration that is temperature stable, free from radio interference and producing more output level and sustain than the Classic Fuzz. It produces a distinctive rich-biting sound that makes solos extremely noticeable but not thin sounding and weedy like so many popular mass marketed effects. The unit has a high input impedance to keep the guitars character and quality of tone whist providing great sustain. It is definitely best described as fuzz rather than distortion but has the ability to be used on chords as well as solos
