Eurorack modules with character and utility

Tube, discrete, and practical modules built for everyday use.

Featured Modules

A few of our favorite tools for adding character, utility, and flexibility to a system.

Metallic tones, odd harmonics, and movement with more personality than a generic ring mod.

Real spring ambience and feedback-friendly texture for patches that need space and movement.

A direct, old-school filter voice for leads, basses, percussion, and hands-on tone shaping.

Our modules are assembled, calibrated, tested, and packaged in-house in Arizona.

We fulfill our own orders to keep fulfillment fast and accurate.

We support, repair, and offer replacement parts when available for all of our modules.

Stoel Music Systems is an American manufacturer of Eurorack modules focused on useful design, distinctive sound, and durable construction.
