OWL Pedal

OWL input front
The OWL Pedal is an open source, programmable stage effects pedal, made for guitarists, musicians, hackers and programmers. Users can program their own effects, or download ready-made patches from our growing online patch library.

Backed by an active community it boasts more than 150 patches, including polyphonic synthesisers, drum machines, glitchers, phasers, flangers, loopers, droners, delays, reverbs, crushers, shapers, screamers, laughers and more. 40 of these patches come pre-loaded, with the possibility of storing your own selection on the device. Without question, the OWL is the most advanced and versatile effects pedal around. It is powered by standard 9v DC or USB, and you don’t need to connect a computer to use it.

For more information, patches, news and documentation see the OpenWareLaboratory website.
