Masco MU-17 - Instrument preset

Close · 78/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Masco MU-17 is a compact mixer-amplifier unit combining mixing and amplification in a single chassis, produced for broadcasting, recording, and sound reinforcement use. Its design prioritizes low noise and flat frequency response over tonal character, making it functionally different from instrument amplifiers of the same era. The MU-17 is primarily of interest to broadcast history collectors rather than guitar players.

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.
