"Yamaha FVX-1 - Mint Condition, Original Box, Fully Tested

For sale is a mint Yamaha FVX-1 vocal effects processor. An increasingly hard-to-find gem from the late ’80s/early ’90s. This unit has lived its entire life in a box, in a smoke-free environment, shows virtually no cosmetic wear, and functions 100 % as intended.

Highlights

Condition: Mint. No damage, rack rash, or faded lettering
Functionality: Every function, button, display segment, MIDI port, and audio I/O has been tested and works flawlessly.
Includes: Original factory box with internal foam inserts (a collector’s bonus)
Power: 230 V EU model (step-down transformer required in 100–120 V regions)
Shipping: I pack to survive world tours—double-boxed, fully insured, and try to ship within 48 h
This is the cleanest FVX-1 I’ve seen in years; perfect for serious collectors or anyone who wants classic Yamaha formant-shifting and vocoder textures without hunting down spare parts."
