There's obvious variation between basses, and we're not going to tell pros like John Myung, Will Lee or Tony Levin that they're wrong for sticking to 34" scales on their basses. In my case, I have been thinking about multiscale in some form for literally decades, mentally chasing a "piano string" low B that has eluded me. I've owned only one 5-string, and was never happy with its low B. The fundamental B just didn't "speak" and I knew I was hearing more overtones than fundamental. I even went High C, eventually, before getting rid of it and using 4-strings for over a decade now.
I'm not a professional musician, however, and can't justify the expense of a Dingwall even if I liked they way they look, which I don't. Spector's recent NS Dimension MS 5 is more my style, and I may end up geting one. (Neck-through is another selling point for me.) I do want that 36" or 37" low B, but on a budget, and none of the current lower cost mutiscales offer that. I'm not in a rush to buy anything, but that's where my head is at. There are Steinway concert grand pianos where I work, and when I go to one and hit a low B ... that's what I want!
