This unit functions well and sounds great. I just changed the internal battery today (October 24th).

There are a two or three buttons that work fine but don’t click the same way the others do when pressed in but they work. “Parameter“ and “Palette” are the main ones. This module is tested thoroughly however. There is some wear, build-up, scratches. All things you would expect with a three decade old device. Outer border of the PCM slot wiggles slightly. Doesn’t affect anything. Device could use some dusting. I factory reset this so you would have all the classic sounds on there. MIDI and audio routing work great. Screen is a little less clear than some other units, but is legible and working fine.

I ship items out either the day of the order or the morning of the next day (except Sunday).
