Some other boutique E or B strings also have the 36.5" scale, including the special order B strings Ken Smith gets from GHS; and I think La Bella as well (36.5" or 36.75") to specifically fit traditional Fender-style instruments with 34-inch scale, top-load plate bridge, and 4-in-line tuners.I've researched this particular bass enough to know the low B needs to be between 37" and 37.75" in winding length to fit properly thru-body. "Long Scale" by most major manufacturers (GHS, Ernie Ball, D'Addario, Dunlop, Rotosound, SIT, etc.) are 37"-37.25" these days, so that should fit this bass just fine. The only notable exception is Elixir, whose "long scale" is 36.5", which is long enough for top-loading but probably a bit too short for thru-body on this bass.
