Kawai (Teisco) S-100P Synthesizer Chorus The JHS SD-1 is aAn interesting analogue monophonic preset synthesizer from 1979 for sale fully serviced and in excellent condition. Identical to the Teisco version (rebadged after Kawai bought the company). Although it is ostensibly a preset synth it has various ways to manipulate the sounds (some of which are quite odd to begin with). Has aftertouch and spring reverb, not to mention fair amount of ARP Pro Soloist DNA in there as well see the comments thread below
