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

Additional SYNTH CITY Listings
"The Polysix is a 6 voice analog polysynth with VCOs as opposed to the somewhat more familiar DCOs in similar keyboards of the time. This synth has a soft and warm sound likely due to those VCOs. There are also 32 preset slots available, ensemble and chorus effects and an arpeggiator.
This is a great sounding analog poly that gives more popular synths like the Roland Juno a run for its money.
Cosmetically, the wood sides are very worn, plenty of blemsihes throughout. Please see detailed photos."
