Professor’s Notes
The Crayon is no ordinary overdrive—it’s color in motion. From glassy edge-of-breakup shimmer to saturated grit, it paints your tone with harmonics that breathe. Open, articulate, and full of character, it lets your playing shine through the mix instead of hiding behind it. Subtle or bold, this is overdrive with personality—and the Professor loves a little color. Professor's Tip: Stack the Crayon before a fuzz or distortion to tighten the low end and add harmonic richness that cuts through layered tones.

Description
The Electro-Harmonix Crayon is a full-range overdrive designed to preserve clarity and dynamics while adding natural grit and warmth. Unlike traditional mid-focused drives, the Crayon offers independent Bass and Treble controls, giving players precise tonal shaping across the entire frequency spectrum. From smooth, transparent boosts to rich, singing overdrive, it adapts beautifully to guitars, basses, and even synths.

Its highly touch-sensitive circuit responds effortlessly to playing dynamics and pickup output, making it just as comfortable pushing an amp into creamy breakup as it is sitting at the front of a pedal chain as a tone enhancer. The Crayon delivers clarity where you want it, growl where you need it, and balance that always cuts through the mix.
