I'd say about a fourth or a third of the music I play regularly I need to tune down to D or even C#. Right now I only have one main bass, my FBB, but am considering getting a second one just for the purpose of not having to constantly tune my 8 string back and forth between standard tuning and dropped D tuning. Anyway, my question is would it be feasible to get a thin gauge B string and tune it UP to D or C# rather than the usual tuning an E down and leaving the string somewhat floppy. I imagine a B tuned up would have much more clarity than a dropped E. Has anybody tried this? Thoughts? Comments?
