I've picked up a beautiful bass neck + body that needs some building up. Everything except the wooden bits, and I mean literally everything. How on earth am I to determine proper string spacing at the bridge and over my pickups with no tuners or bridge? It's a 5-string (soon to be fretless) bass with a nut width of 45 mm and is a 34" scale. I haven't the slightest clue as to the math or procedures necessary to determine proper string spacing. The pickup routs are quite large (109 mm x 32.5 mm) and they are both the same size (neck and bridge). I have paired this with a set of bartolini P25CBC pickups. I would love to be able to use something like a Hipshot KickAss bridge but would like to be sure that's within the realm of possibility depending on what proper string spacing I end up requiring. I am willing and able to provide any and all dimensions I may need. Thanks in advance for your help.
