Is there any reason why speaker jacks can sometimes have a fatter shroud than instrument cable/standard 1/4" jacks?
The reason I am asking is because I'm making my own 4 core speaker cable up with two 1/4" jacks at either end and wondered if instrument cable jacks are suitable.
The first image is 1/4" speaker cable jack plug, and the second is instrument cable. Jack plugs are not so common in home audio systems, but more common for live sound and PA systems.
