Hughes & Kettner CoreBlade - Ultra I preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Hughes & Kettner CoreBlade is a four-channel, 100-watt all-tube head (Clean, Drive, Ultra I, Ultra II) running four EL34s. Every channel has its own gain, boost, EQ, presence, resonance and volume, all programmable, with 128 MIDI-recallable presets and H&K's Tube Safety Control. It covers everything from clean to modern high-gain metal from one head.

• Introduced: 2009
• Wattage: 100W

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.
