Traynor TS-120B preset

Verified · 89/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The TS-120B is a 120-watt solid-state Traynor bass amp. High and normal inputs feed a TL071 op-amp stage with gain and a footswitchable FET boost, then active treble, middle and bass controls and a six-band graphic equalizer (50 Hz to 1.6 kHz) that can be switched in by footswitch. A master volume and balanced line output follow, and a discrete transistor power amp with paralleled MJ15015 output devices runs on ±50 V rails.

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.
