Description

Sinner is based on a sine-shaping circuit that applies logarithmic distortion to the input signal, causing ramp, saw, triangular, and similar, signals to be more rounded and approximate a sine wave. It has a few extra features that allow you to twist and wring your signal into much more excruciating and exciting shapes. Part of this is accomplished via a four-quadrant multiplier (4QM), which also offers ring modulation (RM) as well as typical voltage-controlled amplifier (VCA) capability.

Sinner is direct-coupled (DC) all the way through, so you can use it to control and process control voltages (CV) and other DC signals in addition to sculpting audio.
If, after blowing a few speaker cones, you decide you’ve had enough of that fun, it also has a full-bypass toggle switch to change the output to capacitive coupling (AC) and block the DC bias from the signal.
The LED above the switch is lit in DC mode, and off in AC mode. The output LED is bicolor: red for positive signals, green for negative, and gives you something fun to stare at at 3:50 am when you haven’t slept in two days and your vision is a bleary tunnel and everything echoes but you swear you haven’t patched in the delay yet and that tingly feeling in your fingers and cheeks is warning you of something and who cares but wow that flashy thing is hypnotic, isn’t it?
