Classic Optical Envelope

The Carl Martin Classic Optical Envelope is a 100% analog optical compressor pedal designed to deliver classic compression tones with vintage circuit coloration. This compressor pedal features four adjustable parameters: Gain, which sets the input level into the optical circuit; Level, for controlling the output volume; Compression, for setting compression intensity; and Attack, to adjust how quickly the compression engages, ranging from subtle to heavily compressed effects. True bypass switching preserves the clarity of the dry signal when the effect is off. **Features:** - Optical analog compressor pedal - Four control knobs: Gain, Level, Compression, Attack - True bypass switching - Designed for vintage-style compression tones - Compatible with standard pedalboard power supplies
