There is something I do when working on guitars that some of you guys might find helpful. Nothing is more frustrating than having to string a guitar up multiple times when working on it. When you try to save the strings without pulling them through the bridge or back ferules they entangle , and that is a pita. I keep little plastic bags around to put loose parts in so they are separated in drawers. When I take the strings loose on a guitar, I coil them up and stuff them in those little baggies. I do that with 5 strings, the 6th one has nothing to tangle with. The string tries to uncoil in the bag which helps it stay on. This works particularly well with stop tail pieces. I changed the pickups out on one of my guitars tonight using this method. I wanted to compare the pickups to the ones I had in it previously, so there is a possibility that after checking them out I would have wanted to swap them back. Saved me a lot of frustration. I have at times only had short bags, when that is the case I put rubber bands around them to keep the string in.
