info MAINTENANCE / CUSTOM MODS: classic contact issue with buttons, it is possible to clean them, but extreme care it is needed to disassemble the tact switches - follow this pretty handy guide at GUMIELECTRONICS for this purpose.
The CR-8000 sounds good but it does not offer much sound edit, for this reason there are many custom modification around the world. Just have a peek to this gallery:

ROLAND CR-5000 scaled-down version produced in the same year, lacking sync, digit display and some sounds including clap.

ROLAND TR-808 son of the Compurhyhms, maybe the most famous of the bunch.
