James Gramling is the technician behind the name Diabolical Devices who circuit bends drum machines and other noise making boxes. I’ve always loved the Roland TR-707. It’s the super tight kick in so many late 80s EBM and New Beat records. The Roland 727 is the 707′s latin cousin and her sounds are all over mountains of Freestyle tunes that still grace NYC radio. I think it’s really interesting that Big City Music, a traditional music retailer is selling James’s bent machines.
Diabolical’s custom modified TR-707/727 drum machines are capable of producing a whole range of new sounds. We add a bending patch-bay and hard-wired toggle switches which activate different ring modulated, filtered, distorted, and delay/doubling type effects. What “makes” these machines is the added multi-stage pitch oscillators…” – circuit-bent.com
