I am the current owner of Hydragyrum's Baritone.... If I ever decided to part with it, I promised Kevin he'd have first dibs on it, but dont hold your breath Kev....
Mine is currently tuned A to A, with LaBella strings. One thing I am glad that I did was to replace the bass & treble boost/cut knobs for a LP filter & Q switch, the 3way pup selector was replaced with a pan knob~ sonically this opened up the guitars range quite a bit. With the filter open all the way, and the bridge pup on, it has enough bite/snap/twang for honky-tonk & country type rhythm stuff.... The extended range also allows for numerous alternate chord voicings (a capo on the 7th fret would be equivalent to a standard tuning, so there's a ton of new territory)... And when the pan is set towards the neck pup with the filter rolled off, I can pretty much double as a bass player (w/ a pick) if need be!!!!
I have a couple of students who are really into a lot of current metal~ stuff in C, C#, dropped B, etc etc. Instead of bringing a regular guitar and tuning down for our lessons, I use the baritone with a capo and it works fine.
