Arp OMNI 2 Analogue Synthesizer

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

via eBay UK

"This particular one is in superb condition, one of the best I've ever seen in fact. Very little marking to the cabinet and all slider caps still in place! It's no secret Omni's are problematic if not re-capped and serviced. This one has had all the nessecary work done. It has been totally re-capped and many unreliable CMOS IC's changed. It works perfectly thoughout, is fully calibrated and sounds gorgeous! Comes supplied with copy of owners manual.

This synth produces some of the most amazing and iconic synth string sounds there are. Similar in sound to the Arp Solina but souped up with extra features such as a synth section featuring the Arp 4072/5 filter as used in the late Arp Odyssey and Arp 2600. It also has a phaser mode, hollow sound feature, split keyboard with amazing bass synth sounds, and much more in the way of connectivity such as separate outputs for each of the synths sections(bass, strings, synth), XLR out and so on."

Roland RS-09

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

via this auction

"This auction is for a Roland RS-09 analog string synthesizer.

This is the later version of the RS-09 with the selector switches similar to the TR-808 / Jupiter-8 machines.
The RS-09 is capable of creating lush analog string and pad sounds with some programmability.

This RS-09 has been serviced and restored with new tact switches and slider caps. Everything works and sounds as it should, but there are some cosmetic issues.

*NOTE* The plastic end-pieces (cheeks) of the machine are damaged, with a large chunk of plastic missing from the front corner (see photos). This causes the front panel to be a little when lifting the machine. "
