i believe a fender strat or telecaster nut will do the trick.
what may be better than the graphtech one is a fender roller nut. but theres a bit more to installing them. the good thing is the strings move on ball bearings. ive got one on my strat. it was a big help.
you casn check one out here
I hate to rain on the parade here, O Great One, but I believe a Fender roller nut requires a slot in the fingerboard. It will not butt up against the trimmed end of a Gibson-type fingerboard unless raised to the correct level relative to the surface of the fingerboard by means odf a block.
There are products like Mighty Mite roller nuts specifically made for this type of application (Gibson-style nut replacement), but you would have to do some woodwork to get the Fender roller nut to do the job on the Variax 700 electric.
Line6Antonio may choose to correct me on this, but I am pretty certain that I speak the truth! Sorry to be disagreeable, Your Eminence!
[... does this mean you are going to pee in my hat again, Excellency?]
(8>c}... damn! It takes DAYS for that felt to dry!
[Oh, and by the way: although the Graphtech products are super quality, they will not entirely solve the problem unless the string grooves are properly cut. I never experienced any nut binding problems with my Variax 700 electric with the stock Corian nut, for whatever that is worth.]
what you do is put this on wether it be fender or gibson instalation. its not a drop in item in either case . for that matter neither is mity might. i have a mighty mite on my wild kat. neither is an easy job. both are a great improvement over a standard nut when using a tremelo . mity might is tougher to put in..
both require some wood work. on the fender you remove the slot on one side. the mighty might also requires wood work as it sits way too tall from the factory because of its frame.
in either case as you said it has to be put at the right level.to the frets.
ast to the line 6 nut. i had a hard tail 300 so i couldnt say if it binded or not. but it wouldnt surprise me if some did.
so put that hat outside to dry and air out a bit cause i took some vitamins and you know what that does to yer pee. lol
