The ultimate solution for guitarists or bassists who want that time-tested wah sound without having to use a wah-wah pedal, the Classic Optical Envelope pedal is a versatile auto-wah pedal that employs the same opto-technology as the Carl Martin Classic Opto-Compressor. Offering a wide range of sonic options, the Classic Optical Envelope features an FX on/off (buffered) footswitch, three unique filter modes that are selectable via the second footswitch, and onboard controls including Level, Drive, Q, and Tone.

Taking you anywhere from a deep classic '60s-style wah to a funky, sharp '70s disco sound, the Classic Optical Envelope boasts High Pass (HP), Band Pass (BP) and Low Pass (LP) modes. The Low Pass filter mode makes the Classic Optical Envelope a great choice for bassists, too! The Drive control allows you to adjust how sensitive the effect is to your playing style. Turn the Drive knob all the way up and the Classic Optical Envelope is ultra-responsive to your playing nuances and attack. Hit the strings lightly for a softer, darker wah, or hit em' hard for a more dramatic, dynamic, higher-pitched wah. The Tone control is a high-cut filter that filters out the high frequencies as you turn it counter clockwise. Dial in a full frequency range by turning the Tone knob all the way clockwise. The onboard Q knob can take you anywhere from a round, soft, warm-sounding wah (clockwise) to a sharper, more aggressive wah (counter clockwise). The onboard controls work interactively, so if you change the setting on one control, you might have to tweak the settings on the others. Comes inside of a durable, retro-colored diecast housing. Powered by a 9v batter or optional regulated power supply (recommended for optimum response).
