Mooer Yellow Comp Optical Compressor Micro Compact Pedal

For players who want their dynamics polished, their sustain sweetened, and their tone subtly lifted, the Mooer Yellow Comp Optical Compressor delivers the goods — all without eating up valuable pedalboard space.

Built around classic optical compression technology, the Yellow Comp captures that silky, organic compression you’d expect from high-end studio gear. It smooths out your playing without ever feeling stiff or artificial, letting your natural expression shine through whether you're fingerpicking, slapping, or cranking out big, bold chords.

With just three simple controls — Volume, EQ, and Comp — it’s easy to dial in exactly what you need. Boost your output for solos, even out your rhythm work, or gently thicken your clean tone with a touch of warmth and shimmer from the versatile EQ knob. No complicated menus or tweaking sessions — just pure, intuitive tone shaping.

Housed in a rugged, road-ready metal shell and equipped with true bypass switching, the Yellow Comp guarantees your signal stays clean and uncompromised when it's not in use. And thanks to its ultra-compact footprint, it slots neatly into even the busiest of pedalboards.

At Musicmaker, we love gear that punches above its weight — and the Mooer Yellow Comp is a prime example: big, studio-quality tone from a box no bigger than your palm.

If you’re looking to add subtle studio polish or bring rich sustain and punch to your live sound, the Mooer Yellow Comp is your new secret weapon — small enough to forget, powerful enough to never turn off.
