Kitty Hawk Custom Series Preamp - Overdrive preset

Close · 68/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Kitty Hawk Custom Preamp is a rack-mount tube preamplifier unit built for professional players needing flexible tone-shaping in a studio or live rack system. It features multiple gain stages with switchable voicings, covering clean, crunch, and lead tones from a single unit. The Custom Preamp reflects Kitty Hawk's Texas roots — articulate and dynamic, with a slight mid-cut American character.

Schematic-derived preset files for 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.
