The Old Blood Noise Endeavors AB/Y Switcher is a classic passive AB/Y switcher, giving you three mono jacks (A, B, and Y), and the choice of whether Y is connected to A, B, or both. Turn one input into two outputs, or vice versa. No impedance matching, phase correction, etc., just a simple tool for simple applications.

Two footswitches make it easy - on the right, the A&B footswitch sets whether Y is connected to both A and B or only one of them; on the left, the A or B footswitch sets whether A or B is connected to Y when A&B is off. LEDs show you how everything is set. AB/Y can pass signal without power, but the LED indication requires a 9V DC center negative 2.1mm jack power supply capable of 10mA (not included). The art of the AB/Y Switcher is by Holey Kids.
