DIY Eurorack Synth Stuff

Low & High Toms

In the original TR606 the Toms circuits are placed on a separate board and to save some space the low and high tom share a lot of components, essentially ‘joining them at the hip’. The sounds consist of a single Twin T oscillator each which get complemented with a subtle rumble. This rumble is generated by passing white noise through a LPF. Because of the nature of the circuitry some of the modification will effect both sounds. I’ve also added an input with a selection switch to allow for external noise to be added instead of the internal noise source.
