Egnater Tweaker 15 preset

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

The Tweaker 15 is a compact single-channel Egnater amp built around its voicing switches. A JFET input buffer feeds a 12AX7 with Gain, Tight and Bright switches and a Vintage/Hot gain switch, then a treble, middle and bass stack with a three-way US/AC/Brit selector and a Master. A further 12AX7 handles the effects-loop return and a third the long-tailed-pair inverter, driving a pair of 6V6s with an impedance switch.

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.
