909 rimshot replica
The NeinOhNein RIM is a 909 rimshot replica which is optimised for use in modular synthesizers.
It features an easy to follow circuit board, and a conditioned trigger input to be triggered from a wide variety of signals.
It remains true to the original design of sound generating circuitry.
