I'm fairly remote and can't test basses ... I was just in the process of ordering an F Bass BN5, when I read that this 5 string's string spacing is 18mm. This conflicts with other places where I read that it was the "standard" 19mm. Fbass.com was no help; can anyone clarify it for me definitively? Also, that knob configuration ... how does it work? I've liked to have master volume on the bass so that I can change the volume w/o disrupting my sound (balance between pickups). Thanks for the help, gang. Cheers, Tom p.s. It is urgent because they are going to charge my card tomorrow!
