I have searched far and wide and maybe it's due to a headache and lack of perseverance to just try it that I gave up and decided to ask a quick question about grounding.

Can I solder all grounds together and wrap them in a heatshrink tube then connect one wire from those grounds to the back of a volume pot?

Cheers!

think of ground as a trail out of the guitar. What kind of guitar do you have it makes it easier.

What type of guitar doesn't matter. This is an electrical question.

Usually the people who ask that question don't know much about wiring and it saves me a few back and forth replies if they tell me their guitars so I can just quickly paste a diagram.
