Many players think the right position of the bridge is twice the distance from the nut to the 12th fret. However, in this position the tuning will not be correct on all the frets. On Prucha banjos the distance from the nut to the 12th fret is 335 mm( 13 13/16 inches). To place the bridge we add 2-3mm (5/64 -1/8“) to that measurement (totaling 337-338mm)(13 17/64 – 13 5/16“) to get the correct distance from the 12th fret to the bridge center so that it is actually a little closer to the tailpiece. The feet should always be parallel to the frets. In this place, you will have a good tone all along the fingerboard. If the tone from the 12th fret is sharper than it’s harmonic, then the bridge must be moved towards the tailpiece. If the tone is flater, then the bridge should be adjusted toward the neck. We are only talking about a distance of 2-3mm.
