"1980's Roland SK-20 Symphonic Ensemble vintage organ and synthesizer in exceptional condition and in perfect working order. Fully serviced here at Mike & Mike's Guitar Bar, 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 some very minor wear on the wood veneered side panels and some scuffing on the bottom of the enclosure which still retains its large rubber feet. The face of the synth is extremely clean, with bold graphics and all original slider caps and knobs intact."

"In quite good condition. End cheeks have been replaced and a socket added to the rear connecting the keyboard contacts as some of the keys don't contact well (maybe need contacts sorting out),so in theory another keyboard could be used. I had intended making an interface to render this MIDI controllable,which almost worked. The socket is the remnant of that attempt and connects to the keys and the contact bar. The presets work and the synth section,though some sliders are better than others.
