B - F# - B - E - G# - C# - F#
Thats drop d down a step and a half with a high F#,, i.e DADGBEA.
I stuck it on as an experiment (free strings woot!) and I've plumped with this because my band The Colour Pink Is Gay tune to Drop B on sixes and I wanted to try out a high string for once.
Its pretty sweet, I'm really enjoying how I have to adjust my fingerings and think differently; I can't grab a 'familiar' chord shape easily because it isn't there anymore. All my old sweeps sound diminished now too
I think my next tuning will be Ion Dissonance's tuning - once I find out what it is - as I'm really digging pushing my envelope. I thoroughly recommend anybody bored, stuck in a playing rut or inquisitive checks it out too!
FYI, I'm using a set of STHB with a high 008, i.e .008 .010 .013 .017 .030 .042 .052
Never tried it, but always meant to, diminished sweeps sounds like fun though, I always played in B on 6's
