ART coolswitch Specification Guide

A/B-Y switching works two ways. It lets you switch a common
source signal (guitar, bass or keyboard) between two amplifiers
or amp channels. Or conversely, it lets you switch two source
signals (ie, two different guitars) into the same amplifier. A good
quality A/B-Y switcher will also provide LEDs or other indicators
to show whether A, B or Y routing is in effect. The Y routing 
combines both the A and B outputs in parallel so that two 
amplifiers can be driven at once.

The CoolSWITCH provides full A/B-Y switching functionality,
plus parallel Common in/out jacks.

• 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.

• Power: 9V Battery (included)
• Dimensions: 3.75 x 2.5 x 1.5 inches (90mm x 63mm x 40mm)
• Weight: 1lb (454g)

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.
