Our client came to us with the idea to create a new electric guitar replacement humbucker that gives guitarists the ability to play guitar and bass together or separately. Each of the two pickups in A Little Thunder™ can operate independently. A Little Thunder™ uses DSP, Fast Fourier Transform (FFT), and a unique third method to process the organic signal to produce the bass sound.
Saritasa provided full source systems engineering services through the conceptual and prototyping phases for A Little Thunder™. We provided services to assist the client in structuring the research and development processes, and played an advisory role in choosing custom and off-the-shelf parts. The custom electronic humbucker device and DSP firmware were created in close partnership with the client to deliver a production-ready product for the client to hand-off to their chosen manufacturer.
