1980s Yamaha SK-20 Symphonic Ensemble Vintage Strings, Synthesizer & Organ, Serviced w/ Case


+ shipping

Up for sale, a 1980's Yamaha SK-20 Symphonic Ensemble vintage organ and synthesizer in near mint condition and in perfect working order, complete with the original hardshell case. Fully serviced, this Yamaha boasts dedicated synthesizer, organ, and string sections that can be independently mixed together. Featuring a five octave range, the SK-20 also includes a Leslie simulator (with dedicated output), vibrato, attack and sustain rocker switches, a slider for 'brilliance' and a one-octave transpose switch. The keyboard was also one of the first to utilize a form of Yamaha's FM technology.

The Organ section offers a full range of stop levers from 1' to 16', percussion levers with adjustable decay, and controls for overall sustain, brilliance and decay. Very B3-esque in its tonal intent, the organ can also be augmented with Vibrato and Tremolo. The Preset String section is simple yet lush, and arguably the most desirable subset of this vintage keyboard.

The Poly-Synth section is a 7-note polyphonic synthesizer with basic filter, pitch, envelope, and portamento controls. It features two (detunable) oscillators per voice, making it ideal for thick pads. This section features a built-in sustain and the Tremolo and Ensemble chorus effects also apply to this section. Cosmetically, this SK-20 is an extremely well-kept example with pristine graphics and only a light speckling of wear on the back right corner of the enclosure. The keyboard retains all of the original rubber feet, slider caps and knobs.

The original Yamaha-branded hardshell case is included.
