Perfect Circuit Audio (RSS)
"Fully refurbished Roland TR-707 drum machine, with a twist! Added pitch controls and a circuit bending patchbay allow for tons of expirimentation and unique sounds. Disengage the modifications to use it as a classic stock 707, or engage the pitch controls and start plugging in the circuit bending patch cables to explore it's awesome new sonic capabilites.
Pitch Controls
10 by-passable pitch controls have been added, which affect individual sounds or groups corresponding with the volume faders. Each pitch adjustment has a by-pass toggle switch, pitch control, and status LED. This modification works by manipulating the clock frequency of the affected sounds playback. In bypass mode the original clock frequency is received and the original 707 sound is produced. When the pitch adjustment is activated the original clock frequency is replaced by the added external and adjustable clock frequency generators. Pitch ranges from way above to WAY WAY below original clock/pitch.
Circuit Bending Patchbay
In addition to pitch controls, the modification includes a 10 point ROM-based bending interface aka circuit-bending patchbay. Linking these points with patch cables accesses a mixed bag of odd effects, filter, modulated, and otherwise unique sounds. These effects are the result of cross-modulated and otherwise scrambled ROM data being converted to audio. When none of the modifications are engaged these machines will function and sound as Roland intended. Modification only affect audio and all other functions remain functional no matter what mode or modifications are engaged.
Fully Refurbished
In addition to the insanely fun modifications, all units are fully refurbished. All Diabolical Devices TR-707's are completely disassembled and cleaned: the panel/button board, all key contacts, switching outputs, and all faders and cleaned and treated. The DC power input is replaced and the circuit board is treated to prevent future failure (common weak spot). All interface jacks (MIDI, audio in/puts, and sync) are resoldered and inspected. This makes for very reliable instruments, complete with repair warranty.
Comes carefully packed with basic instructions to get you started, and a repair warranty. Basically if it should fail in the future, just send it back, the unit will be repaired and returned to you no charge (excludes physical damage, mechanical components, misuse, and other unreasonable situations).
