I own a 33-36" multiscale six string. The reason I say it should have longer than 35 for the B isn't because I think bass should have longer than 35, but rather because the point of a multiscale is to be able to have a longer B without having to have an overly long G or C. The G on a 35" 5 string is just fine, as the many 35" straight scale basses can attest to. If someone wants a 35" B, there's no good reason to get a multiscale when a straight scale will work just fine. If they wanted a 36"+ B, though, a straight scale wouldn't be ideal, because the thinner strings start to suffer a bit at that scale, IMO. That's when something like a 33-36 or 34-37 multiscale is a good option. I mean, fair play to people who actually want this, I suppose. If you don't like 35" G or C for whatever reason, this is optimal. For what it's worth, I don't think a bass needs to be long scale to get a nice sounding B. I have a straight scale 33" 5 string, and it sounds great. I'm just not entirely sold on multiscales that aren't at least 35.5", I guess, haha.
