6s are awesome. With a good reinforced design, you can either use as is, tune 2-low(bass plus two lower strings) or 2-high(bass plus two higher strings, tuned E-E like a guitar. The first way, it plays exactly like a 4-string or 5 string bass if you want, and the third way, like a 4-string but with the ability to exactly double guitar chords and playing via the two highest strings, but an octave lower. ie - a real "bass guitar".
Very versitile. Very slick. Too wide for my small hands to deal with.(sigh)
Note - it is entirely possible with it set up E-E to play it like a lead insturment and not sound odd. Shred some chords, lay down that melody, and still do bass at the same time. A real eye-opener to hear played this way. Or - play it as it normally is tuned - works great that way as well.
