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 has the J-wire (Pratt Read) keybed and is in good condition. This Pro One was serviced by Synthchaser in February 2026. Work done included:
- Recapped all original tantalum capacitors & power supply capacitors
- Keybed refurbished – new bushings, bus bars & j-wires cleaned
- Cleaned pots & switches
- New power cord & quiet power transformer
- Tuned & calibrated
