Description

Get ready to enhance your performance with the Radial Twin-City Active ABY Amp Switch, an essential tool for any musician. This active ABY switcher and buffer allows you to connect any two amps and drive them simultaneously without any noise, loss of gain, or degradation of your natural guitar tone. Thanks to Radial's highly acclaimed buffering technology and the Drag Control load correction circuitry, your signal remains clean and pure.

The set-and-forget Drag Control compensates for cable signal loss and introduces the perfect amount of loading to replicate the way your guitar and amp interact. To combat ground loops and their associated hum and buzz, the Twin-City is equipped with an isolation transformer on output B. Accompanied by a ground lift switch and 180 polarity reverse switch, this ensures your amplifiers play in phase while reducing noise to a minimum, even with older vintage amps.

As a buffer, the Twin-City lowers the impedance and susceptibility to noise, making it an ideal signal driver for large stages and long cable runs. Like all Radial products, the Twin-City is built from heavy 14 gauge steel, ensuring durability and stability on a busy stage. The EIS - Electronic Impulse Switching ensures unmatched performance without the challenges posed by mechanical switches. Clear, easy to see LEDs provide on-stage switching cues so you know exactly where you are at all times.

Key Features:

  • Buffered ABY with Drag Control load correction
  • Isolated output eliminates hum and buzz
  • 180-degree polarity sets both amps in phase
  • Compact design for an easy fit on any pedalboard
  • Standard 9 volt power supply operation (adapter not included)
  • Constructed from heavy 14 gauge steel for maximum durability
  • EIS - Electronic Impulse Switching for seamless performance
  • Bright, easy to see LEDs for clear on-stage switching cues

Don't waste your time looking for an ABY, just buy this one.

I say that because I went through about five different ABY pedals before I just took the plunge and bought this. I haven't had to worry about tone suckage or even phase issues
