The CoolSWITCH delivers full A/B-Y switching, plus parallel common in/out jacks. It lets you switch a common source signal (guitar, bass, or keyboard) between two amplifiers or amp channels. It also allows you to switch two source signals (like two different guitars) into the same amplifier. The CoolSWITCH features LED indicators to show whether A, B, or Y routing is in effect. The Y-routing combines the A and B outputs in parallel so two amps can be driven at once.
A and B LEDs illuminate to indicate selected signal routing. Both LEDs illuminated indicates Y routing. Dual footswitches permit selective A/B switching or the combining of both A&B as with a Y adapter. Dual common jacks permit connecting something in parallel with the input source "– such as a guitar tuner.

One instrument switching between two amplifiers: a.) Plug your instrument cable into one of the jacks marked Common. If you have a guitar tuner you may connect it to the other Common jack with an extra guitar cord or shielded patch cable.b.) Using two more shielded cables connect the A jack to the input of amp A and the B jack to the input of amp B. c.) Depress the A/B footswitch to select amplifiers. One of the two LEDs will illuminate to tell you which amp is selected. d.) To get both amps working at once, depress the Y footswitch. When both amps are working, both LEDs will be on.
Two instruments being selected for one amplifier: a.) Using shielded guitar cords, plug one instrument into the A jack and the other into the B jack. b.) Using a third shielded cable, connect one of the Common jacks to the input of the amplifier. c.) Now depress the A/B footswitch to select the desired instrument. Please note that is not generally advisable to use the Y function in this setup (i.e. to have both instruments going into the amp at once). d.) The LEDs will indicate that instrument A or B is connected to the amplifier.
