"Used TR-909 in very good condition, does have a few scratches and blems, but for its age it is in very good condition. This one was recently serviced by our in house techs, notes listed below. These boom boom beat machines might have been used in a few songs over the years, possibly a few hits, definitely many cymbal hits and symbolic ones too.

Serial Number: 427074

Service Notes:

Disassembled and cleaned everything. Cleaned panel pcb buttons
Cleaned insides of individual outputs, dirty NC switch contacts were dirty and causing cut-out on main output.
Resoldered master volume pot and other controls. Cleaned controls"
