which nut do i need to replace the black one on my epiphone less paul ?

You need to pay very close attention to the string spacing on your guitar. This nut is for a string spacing of 1-3/8". Epiphone Les pauls have a string spacing at the nut of 1 3/8". USA Gibson Les Pauls have a string spacing of 1-7/16". That 1/16" makes a difference. You make sure you get the right one. The string spacing on this particular nut is 1-3/8" which will also fit an ESP LTD EC series guitar. Graph Tech does make an exact fit for a 1-7/16" Les Paul nut. These are good quality.

Will this fit Ibanez Gio guitar? If not can a nut be recommended?

It needs to match the neck radius and the string width. Measure those two things and if it matches this nut then it should fit. To measure the radius I just made a template from cardboard. Height wise this nut has plenty of stock to be fit to any neck. I think I ended up sanding about 1/8" off the bottom to fit it to my Yamaha se350 (strat style guitar).

Will this fit a Jackson js22 dinky ?

Whatever nut you decide on, some adjustment will be needed. If you don’t have the tools to do it, bring to a luthier. If you do decide to do it, you will need a caliper and some files. Good luck.
