RQLPG is a reinterpretation of the classic west coast circuit in a modern way to offer today's musicians the thrill of using a sacred monster in the most faithful form of the original.

It contains four independent paths, for four sound sources, that can work as:
- Gate acting on the amplitude of the passing signal, like a voltage controlled amplifier,
- Lopass attenuating the signal in amplitude and at the same time, eliminating the acute ones.

- CV OFFSET pot for defining the Level / Gate or Frequency / Lowpass value.
- RESONANCE pot adjust the amount of Resonance without attenuating the passing signal by phase inversion.
Without audio input it can resonate in self-oscillation if pushed beyond the limit.
We will therefore have a sine controllable in tension and pitchable through the CV OFFSET parameter to make percussive sounds and an indescribably versatile and powerful kick drum.

Inputs and outputs:
Each channel has audio input, output connections and a CV input for control the CV OFFSET pot
