Mesa Boogie Mark V - Fat preset

Verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Mark V is the culmination of Mesa Boogie's four-decade development of the Mark series, offering selectable 10, 45, and 90-watt operation and three channels that recreate the tones of every significant Mark amplifier in the lineage — from the original Mark I through the IIC+ and Mark IV. Its unprecedented tonal range makes it simultaneously the most versatile and most historically comprehensive amplifier Mesa has ever produced. Players who own a Mark V effectively own the entire Mesa Boogie Mark lineage in a single chassis.

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.
