Description
The Sequential Circuits Pro-One is a legendary monophonic analog synth prized for its fat bass, searing leads, and incredibly flexible modulation capabilities. Compact yet powerful, it delivers the iconic Prophet-series sound in a hands-on design that’s become a must-have for serious synth players and collectors.
This Pro One is in excellent condition. It includes the original shipping box (and if being shipped, this is the box it will ship to you in) and manual (which has some writing in it). This Pro One was serviced by Synthchaser in September 2025. Work done included:
- Recapped all original tantalum capacitors
- Replaced original unreliable membrane style keybed with Fatar keybed
- Cleaned pots & switches
- Tuned & calibrated
Prospective buyers are welcome to come try it out before purchasing. Local pickup is welcome and encouraged. If being shipped, the instrument will ship in its original shipping box and be insured for the full purchase price, but this is a vintage electronic item, so all sales will be as-is and final. Be aware that the box will have tape and labels added and will not arrive in exactly the same condition as it is now in the photographs. If you wish to keep the shipping box in the same condition as it is in the photos, you will need to pick your order up in person.
International shipping is available for this item, but it cannot be ordered through the website with international shipping. Please contact me if you are an international buyer interested in purchasing this.
