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. Quick Specs - Full-range overdrive with a lush, rich, warm tone - Independent Bass and Treble controls - Compact pedalboard-ready pedal - Ships with a 9V battery and can use an optional 9VDC AC adapter like the EHX 9.6DC-200 psu
