Does a guitar have an input or output jack?
For example, the jack on your guitar or bass is where you plug in the cable, so it's common to refer to it as the input jack. That, however, is incorrect. The jack on your guitar or bass where you plug the cable in--the one you've been calling an input jack all this time--is actually an output jack.
What kind of jack is used for electric guitars?
The most common output jack for electric guitars is the mono jack. It has two lugs: One is the ground, and it's part of the jack's interior or case. The other lug is the hot or primary lead. This lug is part of the long, bent flange that connects to the tip of your instrument cable.
