Hiwatt 200W Dr201 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Hiwatt DR201 is a 200-watt behemoth built for the largest concert stages of the 1970s, running eight EL34 output tubes in push-pull configuration. Handwired by Dave Reeves' team to the same uncompromising military-spec tolerances as the smaller DR103, the DR201 delivers a wall of clean, articulate sound that simply refuses to break up regardless of playing intensity. At these power levels, the amp's transient response becomes almost forensically accurate, making it a favourite for stadium acts who needed every picking nuance to reach the back row without coloration or compression.

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.
