Jack Hertz 975 Report post Posted July 3, 2017 The Delptronics ThunderBell is a classic analog cowbell sound. The circuit is inspired by the great cowbell sound in the Korg KR-55. Like the KR-55, the TR-808, and most other analog drum machines, we model a cowbell by using two tuned square waves. We also include some pseudo-ring-modulation, as did the KR-55.
