Locking nuts have more space in their grooves which allows for thicker strings while normal nuts can only go so far.
Id fancy an 8 string without all the hassle of floyd rose but with locking nuts so i can install an even thicker 8 string and tune to C# (After the Burial tuning on Wolves Within).

Get your guitar properly set-up and a nut cut especially for the gauges you'd like? 
#4
Basses have standard nuts with wider grooves for thicker strings. It's not a big deal to cut an ordinary nut to accommodate thicker strings.

Whaaa? what the hell are you talking about? 

Virtually all of the Septor series 8-strings would work. www.rondomusic.com

You should know that a locking nut pulls strings out of tune. I fudged up and said intonation

Not if you have a sharp headstock angle or properly setup string retainer. I agree it would be a pain in the ass but it would be possible without fine tuners.

Just have the nut cut for the gage you want Plenty of folks use heavy gage strings with regular nuts.

Nuts get replaced all the time; it's not a "Permanent Mod" in the vein of a Sustainer or a Kill switch or adding a third pickup. 
Speaking of permanent mods, you could probably put a locking type nut on almost any 8-string (it *would* be a permanent mod). I'm assuming in all of this, by the way, that you're not really going to be locking anything down, right?

Looking at the 8 string models with locking trems, I see they are all Kahlers. I didnt try a mock build in the custom shop.
I don't own any guitars with double locking trems, but I just assumed Kahler does what FR and Ibanez do.

Sounds like a good idea, but the nut isn't made to be left un clamped. The string gets caught up. Would not recommend it.

A regular nut is like what, $10 usd. Cut the nut to whatever strings you want, and if you want to go back get a new nut. Nobody will ever know.

OTOH, if you rout a fretboard out for a locking nut you cannot go back (easily).

Kyleisthename Looks good, thanks.

And by any chance, does someone know the exact guitar model Justin Lowe used? That green one with Lacoste logo.


you'd have the same issue with a locking nut?
