The Davoli (Krundaal) Show 2/B is a 1967 all-transistor preamp with two identical channels, Normal and Tremolo, each with high and low inputs and its own treble, middle, bass, volume and presence controls on two BC109 stages. The Tremolo channel adds a transistor oscillator with depth and speed. It has no power stage; its output goes to a separate 60-watt Davoli power unit.

Schematic-derived preset files for the Neural DSP Quad Cortex and 16 Fractal and Line 6 modelers: Axe-Fx II/XL/XL+, Axe-Fx III, FM3, FM9, and the full Helix family (Floor, LT, Rack, HX Stomp, HX Stomp XL, Native).

Gridleak extracts amp parameters from original circuit schematics using AI vision — component values, gain staging, tone stack topology, tube types — then generates native preset files for every supported modeler. Every extraction is scored 0–100 and the score is published.
