Carl Martin Classic Optical Envelope

Classic envelope filter/auto-wah effects pedal for guitar or bass guitar that utilizes the same opto-technology as the Carl Martin’s Opto-compressor and provides a variety of cool options. Its first footswitch is for FX on/off (buffered), and the second to select between the three modes (High Pass, Band Pass and Low Pass). Add to this the Level control for overall volume, Drive for how hard the auto-wah will function, Q for adjusting the size of the bandwidth, and Tone which acts as a separate Hi-pass filter, and you have complete control over the FX – from vocal like tones to funky quacks and fat wows. Housed in die-cast housing with mini-knobs and cool retro colour, the pedal can be powered by a 9V battery, but use of a regulated power supply is recommended for optimum response.
