The Crayon is a versatile overdrive with independent Bass and Treble controls and an open frequency range that provides players with a musical alternative to customary mid-focused overdrive pedals. It delivers a range of sounds going from a suggestion of dirt to full-on distortion and is equally impressive all by itself or when driving another overdrive pedal. Dimensions: 70 x 114 x 53 mm. 9V battery included. Optional: 9V EHX 9,6VDC-200 PSU.
