Classic 80's Simmons SDS9 Electronic Drum Brain Unit

via this auction
"It has individual outputs for each sound and trigger inputs with knobs for adjusting sensitivity. It has mono/stereo outputs. There is midi in/out and a separate input for a sequencer, likely a dedicated Simmons one. The Simmons sound is well known from the 80's. The SDS9 has 6 instruments, with Snare / rim which can be mixed together.

The cool thing about this unit is the filters for the snare. It can be tweaked so they sound like strange analogue-sounding squeals and wooshes, the filters are all analogue as far as I can tell, the knobs are fully adjustable, in other words tweaking is infinite. A tiny tweak makes a huge difference to the sound. The user kits can be saved away in the memory. Not sure if the memory battery needs changing or not though after all this time... The unit features a door that covers the Simmons Sound eProm chips. I have seen other proms on Ebay and not sure but I think that you can swap them out for other eProm based sound sounds (Linn Drum etc?)..."
