    I recently had a Kawai R-100 drum machine circuit bent and modified by GumiElectronic. I could not be more satisfied! The mods include a custom attached case with 25 bend switches, an extra 8 bend switches on the top right of the original R-100 case, and all 3 voice ROMS with a ROM switcher installed. You took a standard 1980′s drum machine and made it into a crushing sonic beast!!!

    Also, I can’t say enough about the excellent customer service and communication. I will no doubt be coming back to you for any electronic modification needs I have in the future. Big thanks to GumiElectronic!

    Here is a link to a photo of my R-100: http://farm6.static.flickr.com/5142/5642477080_7d74b504c5_z.jpg

    And here is a link to a short demo video of the machine in action: http://www.youtube.com/watch?v=bdcmX-dBK50

    Thanks again Gumi!
