The Switch & Bait is a simple 2-to-1 switch box, redirecting two audio sources to one output with the flick of a switch. In addition to the toggle switch, I've added a momentary kill switch (that's the red button in the photos), which allows one to temporarily cut the audio signal to the output. Housed in a 3 x 2 x 1.5 inch plastic project box, it should be pointed out that the Switch & Bait is a passive switcher -- it does not require a battery or AC to work -- and as such, will not add gain or signal boost. Terminated with 1/4 inch female jacks, the box can be used in any duo-combination: pairing up microphones, tape players, FX, you name it.
