I have wanted to string my B1 E-C for two reasons.
First, my B1 is unlined and fretless (and doesn't even have line markers on the top side). I feel like a C string would allow me to play things closer to the nut, with better intonation than if I play on a G string closer to the bridge where the notes are closer and less forgiving if I miss by a bit.
Second, I miss the harmonics on the C string.
I haven't restrung my bass though, because I understand something should be done to the nut before I do it.
On the other hand, I love having a B string, not so much because it goes low, but because it allows me more choices of hand position, which I like for combating boredom and keeping things fresh (for myself), and sometimes for combating hand fatigue.
Also, I like to use the upright in instances where I'm playing with horns, and having a B string is handy when I find myself playing in the keys of E-flat, B-flat F or even C.
Consequently, what I REALLY want, though, is a 6 string B1.
I play fretted 4s, 5s and 6s, depending on the playing style and tone I want. However, I find that I'm not playing my 4 and 5 string fretlesses basses much. For me, the only fretless that makes sense is a 6. I like having the choices ever-present.
Anyway, unless and until Barker makes a 6 string upright, I wonder about having 2: a B-G and an E-C.
Aha! So THAT'S why Lee isn't making 6ers! He makes us consider buying two 5ers!
Wahahahaha!
