Korg KR-55 ‘79 modded analog drum machine

This Korg KR-55 drum machine is pure analog awesomeness from the late 70’s. It’s been modified to include the following
1. 808 style kick drum with pitch (p) decay (d) punch (eq) and volume (bd). This is wired to trigger from the back trigger switch and is selectable on the fly.
2. Snare drum pink and white noise level controls
3. Low Tom and high Tom pitch adjustment
4. Cowbell pitch adjustment
5. 6 ring mod frequency adjustments for HH and Cymbal.
6. Ms-20 style filter with cutoff and res. This filter will even self oscillate and can be switched on and off. Coolest part here, it sometimes picks up local radio frequencies!
