Respacing the ‘Badass’ Bridge

Respacing the ‘Badass’ Bridge

I was asked to recut the saddle slots on a “Badass” adjustable bridge fitted to a Gibson SG. The string spacing on the bridge was narrower than the fingerboard, and the adjustable metal saddles had had slots filed in to hold the strings. These were causing the strings to wear and break very easily.

Instead I filed the saddles to remove the existing slots and cut grooves as shown, using fretsaw, triangular and round files. The grooves lead the strings into the correct position before they finish curving round the bridge. The result is unobtrusive, keeps the strings in the right position and (so I hear) no longer causes breakages.

A spate of repairs involving fret buzzing set me thinking about the ideal neck shape. Some people like a flat fingerboard. Lots of people advocate a neck that’s straight at the body and lifts slightly towards the head, as seen in Fig. 1.

Some people vote for a tapering away at the end of the fingerboard, as in Fig. 2.

The reason for all this, of course, is to accommodate the shape of a plucked string, diagramed in Fig. 3.
