I've been wondering lately about whether it would be possible to make an acoustic bass with a string pitched at F#, or even C# (fourths descending from B). Come to think of it, I haven't even seen acoustics with B strings. Is that even possible? By "possible" I mean possible with decent volume; of course you could construct and string one. Doesn't necessarity have to be an acoustic bass guitar, something more similar in size to an upright would be cool too. I know a B will work on one of those. I don't think anyone here actually makes acoustics, but I thought I'd ask anyway. So what do you guys think?
