Bản mod nút Killswitch đơn giản cho đàn guitar Gretsch

A simple mod to add killswitch button to Gretsch electromatic baritone or other similar guitars. It's mounted on the pickup switch and basically just shorts the output jack pins.

It doesn't require any (visible) guitar mods - the only requirement is to slightly file the pickup switcher hole so two thin wires can pass next to it.

The switch is this one: https://www.digikey.com/en/products/detail/apem-inc/ADTSM25RVTR/1798408 although any 12mm SMD pushbutton switch could work.
