The Benjolin is a ‘noise box’ that is ‘bent by design’, meaning that it always has an amount of unpredictability while still being intuitive to play. The Benjolin features two eighteen-octave range voltage controlled oscillators that drive a ‘rungler’ circuit - circuitry that in essence uses a special interference technique feeding back into the oscillators to force them into wild, surprising behaviour. A special, slightly chaotic filter with a unique topology that imparts a layer of all harmonic distortion to the filter outputs is both excited and modulated by the signals from the rungler circuitry, producing sounds between fat drones to grungy noise havoc. The kit is somewhat challenging to build, but with a little patience and accuracy a beginner in DIY can definitely do it successfully.
