Peavey TNT 100 (1974) preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 1974 Peavey TNT is an early all-transistor bass amp from Peavey's first decade. Two inputs feed a discrete transistor gain stage with a Volume control, then a Mid control with a Mid Shift switch, a Treble and Bass network and a Master. A transistor driver feeds an interstage transformer that drives a pair of 2N3055-type output transistors on +/-36 V rails into an 8-ohm load, with a simple bridge-rectified supply.

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.
