Twin-City™ Specifications

The Twin-City ABY is an active switcher that utilizes electronic impulse switching for silent and professional operation on stage. Bright LED indicators provide instant visual feedback and let you know which outputs are active. Drag™ control load correction allows you to optimize the impedance presented to your pickups to recreate the tone of a direct connection from the guitar to the amplifier. Radial's built-in Class-A buffer allows long cable runs without signal loss, and a ground lift eliminates buzz and hum between amplifiers. The Twin-City is constructed from 14-gauge steel for extreme durability, and is easily powered with standard 9V power supplies.
