No, no - wait a second, here:
It's not right to just crank up the tension on a B-E-A-D-G! You need to 'move all the strings over one spot' (which you can't really do because the lengths would be wrong if you moved the same ones over) - What I'm saying is that your old B-string should be more the size of your current E, and the the old E will then be an A, so it should be skinnier, etc...
Not only would they feel real stiff to just tune them up; not only would the harmonics be odd like that, but I don't think we're talking just a little more tension! That'd be LOTS more tension, wouldn't it?!
I've considered trying that too on my 33"-scale 5-er, but I'd get an E-A-D-G 4-string set, and add (sp. order?) a C. I suppose you can buy 5-sets for that from someone, huh?
I dunno - maybe we should ask the guys on the setup forum, but I'm pretty sure it's trouble to tune five half-steps higher on a set of low-B strings.
