VCO+VCF
VCO + Vactrol LPF = Bad Trip ...
... which is pretty much what it is. Combines a switchable square/saw VCO with a vactrol-based resonant low-pass filter for generalised acidic wonkiness. As well as the usual front-panel controls, there are a bunch of trimpots on the back-side of the board to allow you to alter the response of the filter vactrols - depending on the settings you choose, hilarity may well ensue.
Supplied ready to go with a 6HP panel which has been fabricated from 3mm acrylic - mounting hardware (M3x10 machine screws) and a power cable are also provided.
