Gallien-Krueger 700RB preset

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

The 700RB is a solid-state Gallien-Krueger bi-amp bass head. A JFET input with mute and tuner out feeds volume, presence and contour controls, a string-bass switch and an active four-band EQ, then an electronic crossover splits the signal between a 350-watt woofer amp and a 50-watt tweeter amp. It adds a clip LED, an effects loop and a balanced direct out with pre/post and ground-lift switches.

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.
