Magnatone MP-3 / MP-5 - Normal preset

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

Estey-era Magnatone combos that share one chassis: the MP-3 with two 12-inch speakers and the MP-5 with two 15s. A normal channel and a tremolo channel each have high and low gain inputs, and there is tube-driven spring reverb and a lamp-and-LDR tremolo. Two 6CA7/EL34s in push-pull drive the output.

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.
