Marshall DBS 7200 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The DBS 7200 is a 200-watt bass head from Marshall's mid-1990s Dynamic Bass System range, sharing its circuit with the 72115 and 72410 combos. Hi and Lo inputs feed an op-amp Gain stage and a single ECC83 valve stage blended with the solid-state path, with Deep and Bright switches and Lo, Mid and Hi tone. A footswitchable graphic EQ, THAT 4301 compressor, effects loop, line out and DI follow, into a discrete transistor power amp.

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.
