About
GumiElectronic specializes in modification, circuit bending, and repair of vintage drum machines and synthesizers. I aim to provide documentation and tutorials of all my projects for you DIYers out there. But if you don’t have the tools or the time to do the work yourself, I’d be happy to do it for you. Check out the Service page for details.
If you use any of the info on these pages for your projects, it would be very kind of you to mention GumiElectronic in your documentation or link back to this site in an effort to expand the DIY community and knowledge-base.
GumiElectronic has been operated by Josh Gumiela (aka gumi) since 2005.
