Released in 1981, the Roland Jupiter-8 is one of the most celebrated analog synthesizers ever built. Its eight-voice polyphony, resonant filters, and deep modulation architecture gave it a sound that defined a decade of electronic and pop music production. Decades later, it remains a benchmark instrument in studios worldwide.
Like all vintage analog gear, the Jupiter-8 requires attention over time. Voice chips can fail and cause dropouts or tonal inconsistencies. Filter capacitors and analog circuits lose effectiveness with age, subtly degrading sound quality. Potentiometers and faders accumulate wear and become less precise, while keys and MIDI or audio connectors can deteriorate and cause intermittent issues.
Keeping these components in good condition is what keeps a Jupiter-8 sounding like a Jupiter-8.

Rotary potentiometer 50KBx2 for Roland Jupiter-8 main volume.
Rotary potentiometer for Bender. *Note: the original potentiometer is 24mm. This is a 16mm replacement — the locating pin hole in the bender plate therefore requires slight enlargement with a round file. Alternatively, the locating pin can be removed with pliers, but this will eliminate the anti-rotation function.
Toggles Switch 2-position, side to side (not straight position)
3 position toggle switch with 15 mm lever for Roland vintage synthesizers and drum machines. Available with two shaft types, for original style restoration or a more affordable alternative.
