Ceriatone DZ-30 - Normal preset

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

The DZ30 is a hand-built Ceriatone head in the spirit of the Matchless DC-30: three ECC83s and four cathode-biased EL84s with a GZ34 (or twin 5V4) rectifier and no negative feedback. Channel 1 has its own volume and a six-way tone selector; channel 2 has its own volume with treble and bass. Both feed a cut control and a post-PI master, with an effects loop, half-power switch, speaker-phase switch and impedance selector.

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.
