Oberheim Matrix-12 SN P72901

via this auction, also on Reverb

"This is a previously used Oberheim Matrix 12. The Matrix 12 comes straight from our professional recording studio and is in excellent shape. The synthesizer was recently cleaned and serviced giving it longevity and peak performance. The only cosmetic wear you will find is on the wood side paneling, most notably on the left panel; the wood is partially chipped. Overall, this Matrix 12 is in very clean condition and is a prime example of a legendary synthesizer.

Oberheim's Matrix 12 is a legendary analog synthesizer from the mid-eighties that is still the king of analog sounds. One of the fattest, roundest, pleasantly analog synthesizers around! It's long been known for creating some of the thickest and best analog pads, sweeps, buzzes, basses, and textures. It features Matrix Modulation for extremely wild virtual patching for an almost unlimited range of sounds and modulation capabilities!
