From the seller
Gently used OB-X8
Picked up at ROBOTSPEAk only.
A Classic — Evolved Engineered to be the best modern OB ever created, the OB-X8 is a meticulously matched tactile triumph-- an eight-voice polyphonic analog synth combining all of the key features of the legendary OB-X, OB-Xa, and OB-8 products including all the original presets that gave them their signature sounds!
The Oberheim design team exhaustively analyzed and recreated the complex interactions between the various components of each OB-series synth to capture their nuances and character, creating the classic OB sound required to replicate those vintage oscillators, filters, and envelopes.
The result is the most faithful, authoritative renewal of an analog classic possible — with all of the warmth, subtlety, and presence of the originals.The unique design of the expression levers was integral to bringing out performances that made the OB-series synths famous.
And for even greater expressiveness than the originals, the OB-X8 features a premium-quality Fatar keyboard with velocity and aftertouch sensitivity. Dig in with both hands for sizzling filter sweeps, intense vibrato, and more.
