Radial Engineering

collapse expand iconDescription

The Radial BigShot ABY is a compact ABY switcher that enables you to switch between two amplifiers or combine the signal when you want both amps to play at the same time.

This true-bypass ABY switcher is completely passive meaning that there are no tone altering buffers between the guitar and the amplifier. With the BigShot ABY, you get the pure tone from your guitar plugged direct into your amp. To add versatility, the BigShot ABY is also equipped with a separate tuner out. This 'always on' output feeds your tuner for constant monitoring while keeping it out of the signal chain.

Should you experience hum and buzz problems due to ground loops, the BigShot ABY comes to the rescue with a built-in isolation transformer and ground lift switch. Once engaged, you can toggle the polarity of the second amplifier to ensure both amps play in absolute phase.

In use, the BigShot ABY is simple to use and efficient on stage. When powered by an external 9V supply or pedalboard power brick, full size super-bright LEDs spring to life to provide instant on-stage amplifier status readout. When power is unavailable, the passive audio signal path still works, unaffected. The compact yet ultra-rugged design makes the BigShot ABY ideal for pedalboards where space is always at a premium.

    I run a 2 amp set up so having the ground lift and phase switch is great. Easy to use. No noise when switching.

  • Just get one.

    Got it to run a Sovtec MiG 50 and a Vox AC15. No ground loop or phase issues at all out of the box. It does the job well

  • Love this Box so much

    I really love this box because it solved my problem and as a result has been maybe the most important part of my live setup for over a decade...while the switching between amps is the most obvious use, I was trying to find a way to switch between electric (to my amp) and acoustic (to the PA) while still having access to one pedal chain (most for the tuner for acoustic obviously). This box does the job perfectly. And because it's true bypass, it simply switches with no issue; no hiss, no noise, etc. If for some reason you do run into any ground issues or anything of the link, the switches on the front take care of it. I have the older black face model with no LEDs (therefore no power needed), and really can't recommend this box enough. Far and away the BEST AB box I've ever used, and the last one I ever bought.

  • Great switcher.

    This is a fantastic switcher. I was a little hesitant about using it for 2 amps since it does not have a buffer, however, the volume drop is minimal, and since it's true bypass, it doesn't color your guitar tone at all. It's also built like a tank and operates quietly. Fortunately I haven't had to use any of the toggle switches, but it's good they're there for a variety of setups.

  • An excellent switching pedal

    In my personal studio I use this switching pedal to go between two different sound rigs that I use for live sound. It's a complicated setup but with this pedal, it makes my choices for sound very simple and easy to change between the two. Super strong construction in this unit and I can see why it gets the highest ratings from its users. My son uses a different brand of switching pedal, but I think he would be very impressed with this one.

  • Excellent ABY pedal!

    I wanted 2 amps in my live rig, and all my musician friends recommended this pedal. After research and testing one I borrowed, there was no reason to keep looking.

    If power is out, how does the circuitry isolate and balance the output to each channel A & B? I want to use one guitar into two amplifiers simultaneously and need to know what passive will sound like if -9vdc isn't available.

    It will sound the same.
