Up for bids is a like new, Boss Dr. Rhythm DR-880 Rhythm Machine. Item comes in the original box and includes the manual, power supply and all the cables. I actually bought this to record with about 2 weeks before my band broke up. Needless to say, I never really got the opportunity to used it more than two or three times. Shipping is $20 in the US only.

The Boss Dr. Rhythm DR-880 Rhythm Machine is a rhythm-programming powerhouse loaded with world-class drum, percussion, and bass sounds from Roland's famous SRX library. It also includes a stunning collection of original waveforms. You can get microscopic in programming the DR-880, but you also have the option of taking the simple route with its 3 EZ Compose buttons that allow original patterns to be constructed without note-by-note programming hassles. Patterns can be taken deeper with the Groove Modify feature, where various groove and triplet feels can be applied. Ghost notes and fills can also be added automatically. Guitar and bass players can join the action by plugging directly to the DR-880's Guitar/Bass Input jack, and playing through the built-in COSM Drive/amp models and multi-effects.
