The Crayon does clean up quite a bit, with Volume and Gain, a two-band EQ with two independent controls, and Bass and Treble controls designed for a wide range of usable tones.
The Electro-Harmonix Crayon Full Range pedal is designed to overdrive the full frequency range of the signal, unlike most overdrives which concentrate on the midrange frequencies.
There’s a Volume control to adjust the pedals output level, and a Gain control to adjust the amount of overdrive applied to the signal, from a very subtle crunch to a heavy distortion. There are: a two-band EQ with two independent controls, and Bass and Treble controls which are designed to enable a wide range of usable tones, including the sound of midrange boosting overdrives.
The Electro-Harmonix Crayon Full Range Overdrive features true bypass for an un-corrupted signal through the pedal when in the off position. The on/off button also makes use of a green LED indicator light. The pedal is powered by a standard 9-volt battery, or with an external 9-volt power supply. It has a sturdy and compact build, designed for years of use and for easily fitting into a pedal board.
