Zinky Blue Velvet - Overdrive preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Blue Velvet is a valve amp from Zinky, the company founded by former Fender amp designer Bruce Zinky. A triode input stage feeds relay-switched clean and overdrive channels: clean has two Gain and two Tone controls, a Mid Cut/Boost switch and its own Volume; overdrive adds cascaded triode stages, its own Tone controls and Volume. An effects loop, valve-driven spring reverb and long-tailed pair feed two output pentodes.
