The unit powers on and has been tested through the main audio output. All six drum voices produce sound, including bass drum, snare, rim, high tom, medium tom and low tom.
The front-panel auto-trigger function was used for testing. The tuning and sound controls alter the drum sounds, and the kit number, bank selection, play/program modes, display and indicator lights are working.
The unit is in good vintage cosmetic condition
Simmons SDS9 module only. No drum pads, stand or other accessories are included.
