Sequential Circuits Pro One

“Very good condition and comes with Turbo CPU/MIDI, plus a top of the line Fatar keybed installed. this work costed around £450 just for the parts and so the synth is priced higher than the usual selling price to account for these highly functional upgrades.

The synth sounds perfect and was serviced when the MIDI and keybed upgrades were installed.

The Turbo upgrade gives full MIDI in and out functionality, as well as a number of other extended functions compared to the original.

The Fatar keybed replaces the often dodgy original keys with a top of the range set, the same as is used by manufacturers of new premium synths.

Note that this is a vintage piece of gear and as such does show expected signs of age cosmetically.” Click here to search for synths on eBay
