Vintage Analog BOSS DR-110 Modded

via this auction
"modified Boss DR-110 with MIDI sync, voice mutes, & trigger outputs. This is an incredibly fun drum machine, and one of the nicest looking modified DR-110 that I've ever seen. It's housed in a nicely built, stained oak box with a laminated face plate.

Features:
* MIDI input for syncronizing internal sequencer. There is an internal/external clock switch, so it can also operate on it's own.
* Each voice has it's own mute switch, so you can add / remove drums from the "mix". This mod alone makes this MUCH more flexible than a stock DR-110.
* Each voice also has a trigger output, so this DR-110 can be used to control other analog drums, trigger envelopes, etc. When you mute the drums, the trigger output still works - allowing more flexibility.
* There are also sync / start and stop jacks on the back,
* 9V battery for memory backup.
* works with 9-12v DC standard adaptater (not included)
