Radial Bigshot ABY

A classic "two-amp" setup revisited in V2

The ABY format is essential whenever you want to use two amps (or two signal chains): a combo for crunch and a second amp for clean tones, a "dry" amp and an effects-dedicated amp, or simply two complementary colors on stage. The BigShot ABY V2 follows this logic with a deliberately simple, robust, and transparent approach: a passive selector designed to solve the real problems of dual-amp setups (hum and phase) without complicating your pedalboard.

For whom, which styles, and in what contexts?

The Radial BigShot ABY V2 is aimed at guitarists (and bassists) who want to control a two-amp rig hassle-free: from blues to rock, indie to metal, and even ambient setups where "dry" and "wet" are separated. On stage, it facilitates quick A/B switching and "A+B" activation with your foot. In the studio, it allows capturing two amp characters simultaneously while keeping a tuner output available for clean tuning between takes.
