16HP summing mixer with characterful valve saturation and distortion.
Rabbit Hole is a hybrid solid-state and vacuum tube design. It has two input channels with independent vintage VCAs. The outputs of the VCAs are summed and passed to a solid-state Drive circuit which at higher gain settings hard clips the signal before entering the starved cathode dual-triode vacuum tube. The OWTH - Off With Their Heads diode LED clipping circuit can be engaged for further distortion.
Rabbit Hole is capable of adding subtle warmth or total audio destruction. The Curiouser expander module adds an additional 2 inputs. Multiple Curiouser modules can be daisy-chained to suit your mixing requirements.
