Frequently Asked Questions

It's a subtle, musical overdrive, adding warmth and slight grit—not a harsh distortion. Think of it as a gentle saturation, rather than a full-blown fuzz.
Like all analog VCAs, there's a minimal amount of inherent noise, but the 'clean' output is very well-managed and significantly quieter than the vintage output.
The attenuators handle bipolar signals without clipping, but the range is limited, so extreme bipolar CV signals might require external attenuation for full control.
