Pearl Pk-701 Ultrarare Polyphonic Keyboard Synth

Note: Auction links are affiliate links for which the site may be compensated.


via this Reverb listing

This appears to be the first post to feature the Pearl Pk-701.

"Extremely rare synth by Pearl, produced in very limited numbers with very little documentation available online.

It resembles an Italian-style string machine with piano, string, and brass sounds, featuring a beautiful chorus and vibrato. In reality, it’s a true 8-voice polyphonic synthesizer with an absolutely beautiful sound.

Cosmetically is in great condition, unfortunately, there are no schematics available, and I haven’t been able to tune the individual voices. Each voice has 4 potentiometers, but without documentation, it’s difficult to tune everything properly.

All the voice boards work perfectly, although the slot for board 2 doesn’t output piano sounds on the assigned note."

via this Reverb listing

"The Kawai 100F (also known as the Teisco 100F) is a 1977 Japanese monophonic analogue synthesizer prized for its rich sound and versatile modulation despite a single VCO design. It features saw and square waveforms, a resonant 24dB/oct low-pass filter, non-resonant high-pass filter, noise generator, external input, dual envelope generators, flexible LFO, and three-mode portamento. The VCO’s unique "Low" mode enables sub-audio modulation. Its expressive filter and modulation options made it a creative tool in early electronic music, notably used by Vince Clarke on Depeche Mode’s Photographic."
