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.Technical specifications

Questions frequently asked
Does the Radial BigShot ABY allow the use of two amps at the same time?
Two footswitches enable selecting A or B, then activating the Both mode to send the signal to both 6.35 mm jack outputs.
How to eliminate a ground loop with two amps?
The B output features a switchable isolation transformer and a ground lift switch. This configuration aims to reduce hum caused by ground loops. A 180° phase inverter is available when the isolation is engaged.
Is power required for this ABY pedal?
The passive audio path operates without power. A 9 V DC center-negative supply of at least 120 mA is used only for the status LEDs.
Can a tuner be plugged permanently into this ABY switcher?
A separate Tuner output in 6.35 mm jack format remains active at all times, allowing a tuner to be left connected.
How much space does the BigShot ABY take on a pedalboard?
The 1.9 mm thick steel enclosure measures 92 x 99 x 51 mm and weighs 560 g.
