VCA with a mini-tube, featuring a feedback circuit and a bias voltage switch.
A VCA module using a Russian mini-tube, made by Klangbau Köln.
It features a gain knob and a switch for the tube's bias voltage (to achieve a different saturation sound), a CV input, two audio inputs and an audio output - all with attenuators.
The second audio input is normalled to the first input, which lets you add feedback.
Produces a real warm and compressed tube sound. With feedback creat fuzzy sounds with subharmonic content, realy surprising.
It work also like a wavefolder, input a sinewave and fold it in the tube manner.
It consumes only 30ma and don´t get warm or hot, as you my expect., no extra power supply, works also with +-15V .
With 9hp black frontpanel avialable, please ask.
Oct 2018: A 35mm deep version available, please ask me!
