ADG is happy to announce the release of AC MASTER from Tsakalis Audioworks. Paying homage to the British cranked amps of the 60s, AC MASTER carries a retro flavour with its VOX-style overdrive and Range Master inspired boost circuit.
AC MASTER is available for shipping from ADG late April 2026
Designed for players who love the sound of classic 60s British amplifiers pushed to their limits, the AC MASTER from Tsakalis Audioworks combines two classic British circuits in a single pedal, a VOX-style overdrive and a Range Master inspired booster. AC MASTER offers immediate access to the iconic tones associated with players like Brian May and Rory Gallagher, while also covering a wide range of modern drive and boost applications.
Used independently or stacked together, the two sections provide everything from sparkling edge-of-breakup, sweet-singing overdrive tones to aggressive classic rock saturation.
