The OWL by Rebel Technology (£249.00) is an open source, programmable pedal made for musicians, hackers, and programmers alike. The thought of coders being able to create their own effects and put them in a stompbox is very exciting. It will run, among other programming options, Cycling 74’s Max MSP. For non-programmers, it comes with pre-loaded with 40 patches and there is an online library where you can download over 150 more, including polyphonic synthesizers, drum machines, glitchers, phasers, flangers, loopers, droners, delays, reverbs, crushers, shapers, screamers, laughers and more. Without MIDI to quickly access various patches, it strikes me as either a cool studio tool, or a way to add one truly or two unique sounds to your board.
Fair cheaper to buy an arduino “guitar pedal” kit and make one for yourself. Huge DSP libraries on the internet already for effect files to tweak to your hearts content.
Altering numbers in a file is bit less messy than a soldering iron and resisters 🙂
