Solton BV60 preset

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

The Solton BV60 is a single-channel valve head. Two inputs feed one ECC83 gain stage, a Treble/Bass/Middle stack, then Presence and Volume controls ahead of a second ECC83 stage. The second ECC83 is a DC-coupled amplifier into a split-load phase inverter with negative feedback at its cathode, driving two EL34s with adjustable fixed bias. A silicon-diode supply runs about 440 V, with a standby switch and 5- and 15-ohm outputs.

Schematic-derived preset files for the Neural DSP Quad Cortex and 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.
