Ampeg BA-115HPT preset

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

The BA-115HPT is a solid-state Ampeg bass combo in the BA series, a single 15-inch speaker cab with a high-frequency horn. Its circuit uses an NE5532 op-amp preamp feeding a MOSFET output stage, and it differs from the plain BA-115HP. It is a practice and small-gig bass amp aimed at players who want Ampeg tone controls in one portable box.

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.
