The Carl Martin Classic Optical Envelope essentially a classic envelope filter (auto-wah utilizing the same Opto-technology as the Opto-compressor) for guitar or bass, with a bunch of cool options. The first foot switch 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 your FX…from vocal like tones to funky quacks and fat wows! Housed in the cool new die-cast housing with mini-knobs and cool retro colour, the Classic Optical Envelope can be powered by a 9v battery, but recommend a regulated power supply for optimum response!
