Ground loop

I'm new to the DIY without instructions idea (which doesnt make anysense) and I don't know much about proper grounding.

I plan on making a double delay and reverb in one box. Lined up Delay -> Delay -> Reverb. There is going to be 1 in and 1 out. All three circuit boards are going to be individually truebypassed.

What I was thinking is I could just get a scratch piece of veroboard and connect all the grounds there, then one to the power lug ground. I've heard about ground loop trouble, but I don't totally understand. Any useful tips or anything you can offer would be great

I believe that the method you are proposing is correct, If you connect all of the grounds to a single point, there is no "loop" established that can cause trouble. If you ground to various points you can set up multiple paths to ground which will allow current to flow where you don't want it.

Alright, so grounds dont necessarily have to go in a linear fashion. Like one grounded thing, to the next, to the next, they can merge together at different points, correct?

That doesnt seem to difficult, as long as you keep all your bases covered.

What do you mean by having it flow where you dont want it? Like back into the circuit?

Ground loops are caused by having more than one path to ground. As long as that portion of the circuit only has one path to ground it is fine.

Humbucker pickup circuits do not seem as seceptable to ground loop problems. I typically run a ground from the output jack to the back of the Volume pot then run a ground from the back of that pot to other controls (one separate one for each). I have gotten to where I like the bridge run by itself straight to the output jack.

Where you can get into trouble is when your control pots are mounted on the back of a common control plate (metal) and you run grounds to the back of the pots. In that case you have 2 or more paths to ground, one being the metal control plate where all the metal pots come in contact and the ground wire you ran to the back of each control. In that case I would run only one ground wire to the back of one pot and let the control plate do the rest.

First time I've seen this kind of spam on a forum. {censored} you.
