Updates
For the time being we are selling on eBay and are starting to release new modules -- please search for Circuit Slices modules there. Using eBay has kept our prices low. Our new ring modulator has a built-in VCA and only takes up 4HP in your rack. We also have added an LFO to our line of high-quality, SMT-produced, and very affordable eurorack modules.

Affordable Quality
Eurorack Format Modules
Affordable Quality
Our modules use state-of-the-art components assembled using current surface-mount, "pick & place", production techniques. Classic analog designs are updated with new low-noise op-amps and cost effective components. And prices are reduced by selling directly to the customer -- avoiding the 30% to 40% markup required by many distributors.
