I'm building a 6 string bass at the moment, but they're generally tuned BEADGB, I can't personally see the advantage of EADGBE on a bass, it'll just take you needlessly higher, whereas BEADGB will take you lower and higher (which is was I want it for).
That neck does look crazily thin, as do the strings, anyone know what the string thicknesses are on them?
Totally digging the beatles minis! Anyone ever seen pics of Ringo Starr's mini? He had it modified as a hatchback with no back seats so he could easily get his drumkit in and out of it!

Doesn't show too well in that pic, but you get the idea.
