Let's try to settle this. On my OB-5, at the bridge I'm measuring 72mm from middle of B to middle of G. We divide that by 4 and get 18mm spacing. Just for comparison's sake, on my Peavey Cirrus (bolt-on) 5, it is 17.5mm. Care to measure your OB-J5? It sure looks wider, but that could just be the photograph.
freshly measured specs:
- nut width: 1 3/4"
- string spacing: 18mm
- board width at end of board: 2 7/8"
