I got my first 5 string back in 2001, a carvin bb75p. I just never favored the sound of the low b. I had owned 2 six strings, and have sold both. I've got an ergo eub with a lowB on order however. I haven't played a bass with a low B that I really like. I'd love to check out a six string dingwall, but other than those, i can't see myself ever using a 34" or 35" scale instrument with a lowB.On switching, You will have to change the nut though, and unless your favorite string company makes highC sets, you'll have to piecemeal them together. I'm a rotosound fan, and can't find the six string sets, so I just buy a set of RS66 Roto's and get an individual string, around .030, sometimes bass strings, sometimes guitar strings, depenends on what is in stock, and use those.
