Ceriatone Hey What?! 103 - Normal preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Hey What?! 103 is Ceriatone's take on the Hiwatt DR103: three ECC83s, a 12AT7 phase inverter and four EL34s for 100 watts. Normal and Bright channels can be jumpered, sharing bass/treble/middle, presence and master. It delivers the huge, clear, punchy Hiwatt clean and a firm, articulate crunch when pushed.

• Made in: Malaysia

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.
