Up for sale is a vintage Whirlwind Selector A/B/Y Box. Built like a tank with a heavy-duty metal enclosure, this industry-standard switcher allows you to seamlessly toggle between two amps, combine two amps at once, or switch between two instruments sharing a single input.
Featuring a 100% passive audio circuit, the Selector keeps your signal path completely transparent with zero tone suck. Power (9V DC or internal battery) is strictly used to run the status LEDs, so your signal will pass even if power is disconnected on stage.
Features:
A/B Toggle: Instantly switches between Output A and Output B.
BOTH Switch: Combines Outputs A and B for dual-amp operation.
Passive Circuitry: True audio transparency without active buffer coloration.
Connections: 1/4" Input/Output main port, 1/4" A and B jacks, 9V DC jack.
Condition:
Fully tested and 100% functional.
Heavy-duty mechanical switches actuate cleanly.
Normal cosmetic surface wear on the housing and graphic print from light use (see photos for exact condition).
