Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The SVT-300 is the solid-state equivalent of the tube SVT, delivering 300 watts of clean, reliable bass power. While lacking the harmonic warmth of its tube counterpart, the SVT-300 offered touring reliability and consistent output for professional bass players who needed the SVT's power without the maintenance demands of a tube 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.
