“Yamaha FB-01 1/2U FM Synthesizer Module (AS IS). Condition is For parts or not working. Shipped with USPS Priority Mail.
The unit is in need of repair. It turns on and all buttons are functional (top right button is a little sticky but it works), however as far as I know it does not produce sound. I tried controlling via MIDI and even tried the machine’s internal sound test with no luck” Click here to search for synths on eBay
