Cool use of NST on a 7 string! That's too rad.
I had my guitar tuned to B, E, A, D, F#, B for years. Basically, standard tuning dropped down a 4th.
I then, later on, applied NST to it, and ended up with G, D, A, E, B, D. Getting me "darn close" to the upper registers of a normal guitar but also quite a bit lower than a regular guitar too. I had to purchase (groan) a Zakk Wylde string set that had a rare .070 in it so I could get that low G without the string being all floppy. It works well, except that I had to file down the nut to accomodate it. Then on the high 5th and 6th strings, I put on a .012 and a .009, respectively. So its a wild extreme of string thicknesses. I have been contemplating raising the 5th an 6th strings higher to...something....since they are so thin they could easily go up 1.5 to 2.5 steps if needed. But I decided a while ago to stick to NST for now, since its a tried and tested tuning. Must be some reason for it. So before I modify it, I continue to study it.
In the end, I call my pawn shop Strat knock-off (that I painted myself, poorly) my "poor man's Chapman Stick" as it allows me a wider range when I play in the bass/guitar & drum duo I play in. If you are wondering what I do with it, check out the
