Sovtek MIG-60 preset

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

The Sovtek MIG-60 is a Russian-built 60-watt tube head from New Sensor's MIG range, drawn as the 'MIG 60 Lead'. It is a single channel with high and low inputs: cascaded 12AX7 stages with a gain control and a cathode follower feed a Treble, Bass and Midrange stack and a Master Volume, then a 12AX7 long-tail inverter with Presence in the feedback loop drives two fixed-bias EL34s, with cathode sense resistors for setting bias. Bridge-rectified supplies, standby, 4/8-ohm outputs and a line out.

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.
