OB 6 KEYBOARD SEQUENTIAL Polyphonic Analog Synthesizer

The OB-6 is a once-in-a-lifetime collaboration between the two most influential designers in the history of poly synthesizers, Dave Smith and Tom Oberheim. The OB-6 takes Tom Oberheim’s classic, bold sound—with its true voltage-controlled oscillators, 2-pole filter, and amplifiers—and adds modern enhancements like studio-quality effects, a polyphonic step sequencer, an arpeggiator, and more. No other modern analog poly synth can boast such a pedigree or such a massive, in-your-face sonic signature.
