Standel's bass amplifier line from the late 1950s and early 1960s was among the first purpose-built bass amplification solutions available to American musicians. Bob Crooks engineered them with extended low-frequency response and clean headroom that was years ahead of competitors. These amps were used by early session bassists in Los Angeles recording studios.

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.
