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

 

Pre-Order an OWL Online

We are in the process of setting up an online shop on the Rebel Technology website where you may pre-order an OWL:

OWL

OWL stands for Open Ware Laboratory which refers to the fact that the entire project is open source in both hardware and software. Being open source is an important issue for us in terms of making all of the technology completely accessible to the end user.

Kickstarter campaign

A first production run of the OWL has been successfully funded via our Kickstarter campaign which recently ended. The campaign ran for a month and thanks to our backers we raised over £33,000 in pre-orders. This is the video that we used to promote the pedal on Kickstarter; it’ll tell you a bit more about the project:

About the Project

The OWL gives users the chance to implement their own bespoke DSP guitar effects and become part of an open-source DSP development community, and for those that don’t develop themselves there is a growing array of ready-made patches available for download in the patch library.

Using a provided C++ framework, applications can be easily developed, compiled and loaded to the on-board ARM Cortex M4 chip, allowing the user to change the function of the pedal without any hardware-specific knowledge.

With a minimum of coding and DSP knowledge, the OWL can become any kind of guitar effect that you can imagine, or a chain of unique effects. Alternatively, you could build a patch comprised of several DSP effects that you could switch between using one of the assignable pots on the pedal.

With a strong emphasis on open-source hardware and software, the OWL is also a good entry-point for those wishing to program their own audio algorithms, or for those wanting to learn more about DSP programming in general.

For developers:

      • Write code for a hardware DSP architecture in plain C/C++
      • Open source platform and tool chain
      • Easy to change and upload patches over USB

For musicians:

      • Load patches from your computer via USB
      • Collection of sample patches available and growing
      • Same input/output characteristics as a standard guitar FX pedal

Patch testing

Here’s another video we made to test out the V2 prototype and some of the initial patches developed for the pedal:
