I tuned my guitar to NST (C-G-D-A-E-G) a while back to see what it was all about, it seemed weird and I ended up tuning back to standard pretty quick. About a month ago I decided to give it another whirl and fell in love with NST, tuning in 5ths extends the range of the instrument so much and having that minor 3rd interval at the top makes it a bit more melodic and less drone-y. I have spent the last month getting acquainted with this tuning and writing a shit ton of songs and riffs. The other day I was watching an Isis video where Aaron Turner was giving a tour of his gear and he was saying that Isis usually tunes to drop-B with the high string also tuned to B (B-F#-B-E-G#-B) but that they sometimes drop the low B down to F# an octave below the next F# (F#-F#-B-E-G#-B). The tuning looked interesting so decided to try and bastardize this Isis tuning with NST. What I ended up with is G-G-D-A-E-G. I have a super low G then a G an octave above then the next 3 strings are tuned in 5ths and then the minor 3rd at the top. With this tuning my 6 string classical guitar has more range than an 8 string! My only issue at this point is that the low G is as floppy as my ball sack on a hot day, I have to find out if I can get a larger gauge nylon string to counter this. If I can't it won't be a huge deal because I am not doing any sort of shredding in this tuning, mostly droning heavy riffs. Has anyone here ever messed around with NST? What did you think of it and did you try to make any variations on it?
