We built the hardware first

Six months, real tubes, Sowter and Lundahl iron — we built a golden unit, then modeled every path of it.

Black Q started life as a physical build: swapping tubes, transformers and signal paths until the unit had super powers. Then we captured both transformer paths and the valve choices in DSP.

Type A gives a full sound with big low end; Type B is crunchier with enhanced mids and highs. Low latency, light on CPU — track through it, stack instances freely.
