The Verbos Electronics Amplitude & Tone Controller is a totally discrete VCA with simultaneous exponential and linear cv input. There is a discrete gain stage on the input and a voltage controlled low-pass filter with diode limited resonance. With careful balancing of the input gain and resonance control a self-oscillation mix with the input signal can be achieved, distorted on the VCA input at your leisure. Separation of the Low-Pass, Amplitude and Resonance controls greatly increases the scope of this excellent rack mod.
