The Classic Optical Envelope is essentially a classic envelope filter (auto-wah utilizing the same opto-technology as the Opto-compressor) for guitar or bass.

The 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 your fx...from vocal like tones to funky quacks and fat wows!

Housed in the cool new diecast housing with mini-knobs and cool retro colour, the Classic Optical Envelope can be powered by a 9v battery, but we always recommend a regulated power supply for optimum response!

For EU customers, taxes are included in the shipping price!
