This an odd one to list.

Full disclosure: years ago I had a go at modding this. Separate drum and synth outs (on rca jacks for some reason???), mute for the synth, three way drum sound mods. I was learning and I'll be honest they are a shocking mess but they WORKED!

Cut back to today and the best part of a decade in a cupboard has not been kind. Drums don't sound as though they work, there's a rubber foot missing, a few dings around the edges and sthe peaker picks up a lot of ground hum, but the synth and sequencer are fine, the switches and knobs feel great, and that lovely growly shrieky MS20 filter is fantastic. The mods are easy to disconnect or redo with a bit more finesse than I managed, and there's no doubt a ton more available (I never bothered with a midi or distortion circuit for example) so this is aimed at someone who wants a project.
