Depends on what your "mental point of reference" is. For me, moving from 4 to 5 was literally effortless. However, moving from 5 to 6 would be something I'd have to work on and stick with. I sort of think of a 5 as a 4 with an extension, whereas the 6 just seems like a whole new instrument. Not sure if that makes sense to everyone, but at least that's the way my brain is wired.![]()
The way I see it...I've worked out so many lines, tunes, changes, fingerings incorporating the use of the B string. Not having it leaves me missing something I once had available to me. I really don't see any novelty in going back. I'd guess if I put that same time into a 6 I would feel the same way. Generally I think it's easier to add then take away at this point. IMO

It's disarmingly awesome and still catches me as it's PERFECT! Doesn't matter where I am on the neck? INCREDIBLE instrument!
