Marshall JVM410HJS - OD1 preset

Close · 66/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The JVM410HJS is Joe Satriani's signature version of the 100-watt, four-channel JVM410H, launched in 2012 after several years of prototypes he used on tour and in the studio. The reverb is gone and each channel gets its own programmable noise gate instead; the gain channels are revoiced with more midrange and less compression, and a programmable scoop switch works on both OD channels.

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.
