I can only speak for my 32" Elwood L by repeating what I have already said elsewhere. When I asked Adrian prior to the build what I could expect from the B-string, he said more or less this, which I can confirm a 100% having owned the bass for two years now.
If you expect a B-string like for example on a Dingwall bass with fanned frets, you will be disappointed. But if you are looking for a B-string with which you can make music, it will work fine.
But is it comparable to a Dingwall with a fanned-fret M bass?

, but have you noticed that there is a new option in the Configurator?
