The Carl Martin Classic Optical Envelope is a versatile auto-wah/envelope filter pedal utilizing premium opto-technology with three filter modes and extensive tone-shaping controls for guitar and bass.

-Premium Opto-Technology - Built using the same high-quality optical technology as Carl Martin's renowned Opto-Compressor, delivering smooth, natural auto-wah response that reacts dynamically to your playing touch and attack intensity

-Three Filter Mode Presets - Select switch offers High Pass (sharp 70s disco sounds), Band Pass (classic vocal-like wah tones), and Low Pass (deep growling 60s wah, ideal for bass guitar), providing everything from funky quacks to fat wows

-Highly Interactive Control Set - Tone control adjusts high-frequency content, Drive dictates sensitivity to string attack, Q knob adjusts bandwidth from soft/wide to sharp/aggressive, and Level maintains signal strength—all controls work interactively for ultimate customization

-Touch-Sensitive Dynamic Response - Envelope filter responds precisely to your playing dynamics, producing softer, darker wah with gentle playing and more dramatic, higher-pitched wah with aggressive attack, perfectly suited to expressive performance styles

-High-Quality Buffered Bypass - Features premium buffered bypass (not true bypass) ensuring silent switching and preventing high-frequency loss through long cable runs or multiple pedals—critical for maintaining full bandwidth envelope filter performance
