Smooth Optical Compression

The Mooer Yellow Comp delivers classic optical compression with a smooth, musical response that enhances your tone without losing its character. Designed to replicate vintage analog compressor behavior, this pedal offers a balanced dynamic control with natural attack and release. Ideal for tightening up rhythm sections or adding sustain to solos, the Yellow Comp ensures every note retains its original transients. Whether you’re playing clean, crunch, or overdriven tones, it enhances clarity and definition across the frequency spectrum without sounding artificial or squashed.

Preserve Your Tone

One of the standout features of the Yellow Comp is its ability to maintain the integrity of your original signal. While many compressors color your tone, Mooer’s optical circuit design works subtly, applying dynamic control only where needed. This means your unique playing dynamics, picking nuance, and tone profile remain intact. With true bypass circuitry, the pedal also ensures zero tonal interference when disengaged—making it an excellent choice for both studio work and live performances.

Compact, Road-Ready Design

Crafted with a full metal shell, the Yellow Comp is built for serious musicians who demand durability and portability. It fits easily into any pedalboard thanks to its micro-sized dimensions (93.5mm x 42mm x 52mm) and weighs only 160g. Despite its small footprint, the build quality is solid, and the layout is intuitive. Mooer’s design philosophy prioritizes simplicity without sacrificing performance, giving players everything they need in a sleek, reliable enclosure.
