The best pro-rig ABY for the road and studio
I've had mine several years now and could not be happier with it. Very useful for my usual set-up. Does everything I need.
I use mine at the end of my pedal board to either ABY between two amps, or to ABY between two channels (like on a Vox AC30 normal and/or top boost, or Hiwatt, etc.) and the 180 Degrees polarity switch eliminates speaker phase issues when using a very old tweed with a newer amp, also, the Lift switch eliminates ground loop hum issues between amps. The load correction feature eliminates "dead-dynamics" issues encountered with most cheap ABY switchers.
It's heavy steel case and solid build is world tour ready. Radial does not make a bad anything. In fact, they are one of the best pro gear makers on the planet. They seem to specialize in building real-world solutions for real working musicians common gear issues. I would send them a Christmas card every year if I ever sent out cards.
