Casio RZ-1 drum machine/sampler. Works great! Recently serviced with new internal battery installed (inside of battery clip for easy future replacement if necessary), new sample-filtering potentiometers installed, no issues whatsoever with functioning. The screen is clear and LEDs all work. Sounds great, all inputs/outputs/faders work.

The case has cosmetic imperfections however, with various scuffs and a large crack in the upper right corner. It is also missing some of the screws. However it still feels sturdy. Will be packed professionally (I pack and ship musical instruments for a living) and will ship out quickly. Thanks for looking!
