“OP-1 that works great with the exception of the onboard mic, which does NOT work. A microphone/instrument can be plugged in and that works fine.
This is how I received it, but has had decksaver and case during ownership.
All buttons, knobs and other inputs and headphones output, as well as the screen work great.
INCLUDES:
Decksaver
Semi-hard zippered Case
Original usb cable
Telescoping radio antenna
OP-1 synthesizer groove box ” Click here to visit listing on eBay
