I'm going to strip the paint off a guitar down to wood.

Clear satin lacquer.

Tung oil on guitars is great.
Also be aware that a lot of cheap guitars look really awful when stripped

This.

I've used BLO in the past and got a nice result, but you must realise that an oil finish will almost no knock protection, however the sustain I got with an oil finish was amazing!

I'd say danish oil or satin poly

I agree with anon 1 and anon 2. Tung oil, all the way. Here's a how-to from

(trimmed to fit character limit)

Almost all experts agree that using a cloth moistened with warm water is the easiest way to raise the grain on your project before oiling. This should be done before you apply tung oil. Raise the grain, sand, and then begin. Apply the oil liberally with a soft cloth or brush and then wipe it off like you mean it. Check after an hour or two, and if extra oil has beaded on the surface, wipe it away. Don’t forget that rags used to apply drying oils are highly combustible.

When using pure tung oil, you need several coats. It’s very important that you thin each coat with the first coat being the thinnest (I recommend 70 percent solvent). Each successive coat should be thicker (less thinned), and the last coat must be the thickest. Your thinner needs to be an organic solvent, one that is carbon based like turpentine, mineral spirits or the newfangled “citrus solvent”.

Every layer except the last must be sanded, so the next layer of tung oil will bond to the previous layer. Three hundred and twenty-grit sandpaper creates the “tooth” that grips the next layer. When sanding between coats, you have to go lightly or you will suddenly sand through one or more previous coats and you will have dreaded witness lines.

Getting good results requires using the right techniques and not being in a hurry. I would allow at least a week between coats, although I have heard of people doing it faster with good results. There are many other finishes better suited to a tight schedule; varnishes, lacquers, and even BLO. However, if you want to use oil, and you have some time to devote to the finish, pure tung oil is in a class by itself. There is no other drying oil that has the same resistance to water, mold, bacteria, yellowing, darkening, but offers strength and flexibility.
