AC Master

The AC MASTER is a dual overdrive and boost pedal combining two independent circuits: a VOX AC30 Top Boost-inspired preamp and a Range Master-inspired treble booster. Both sections can be used independently, stacked together, or separated using the integrated effects loop for flexible pedalboard routing. The AC section recreates the sound of a vintage three-channel AC30, allowing the Normal and Top Boost channels to be blended. It also includes Bass, Treble, Tone Cut, and Master Volume controls for amp-style tone shaping. The MASTER section is based on the classic Range Master treble booster, enhanced with Volume and a three-position Range selector for Treble, Mid, or Bass voicings. It uses a silicon transistor selected to reproduce the response of vintage germanium units while offering greater stability.
