The JHS Active A/B/Y takes one instrument signal and sends it to two outputs: A, B or both at once. It is the box for running two amps, an amp and an interface, or an amp and a mixing desk from one guitar. The left footswitch picks A or B, with the LED red for A and green for B, and the right Y footswitch sends to both.
The input is high impedance and buffered, FET transistors keep the switching silent, and the two outputs are isolated from each other to stop ground loops. The A output runs through a transformer, which removes hum without needing a ground lift, and has a side-mounted polarity reversal switch for when the two rigs cancel each other out. JHS pairs it with the 424 Gain Stage to run an amp and a DI side by side.
