This particular 1965 LG 0, Gibson's entry level student acoustic, came in with the usual plastic bridge problems. It was set up with nickel wound .010s, a warped and unseated plastic bridge and weak tone. The bridge pad was spruce and was badly cracked across the pin holes. The new owner and I opted to replace the bridge pad and bridge with sturdy wooden counterparts for tone and stability. After removing the old bridge pad, I installed a new one made of quartersawn maple. The new bridge was made from a piece of Indian rosewood that wasn't very red/purple and nicely matched the Brazilian fingerboard.
After installing the bridge pad, I took advantage of the opportunity to correct the too narrow string spacing by plugging the old pin holes in the top with matching mahogany, glued in and trimmed flush with a chisel. With a new bridge, pad and plugged pin holes in the top, the new holes would be completely virgin and thus a stable and perfect fit.
Wooden Gibson bridges made in this backwards belly style tend to split across the pins so I made the new bridge subtly wider with more wood behind the pins. Because the plastic bridge is screwed on, the lacquer was never removed beneath it. I stripped the lacquer under the new bridge's footprint to ensure a good glue bond. Unfortunately, I neglected to get any pictures of the clamping for the bridge or pad, but one can imagine the clamps and cauls arranged on the top.
After gluing the bridge on, I calculated the position of the saddle slot and routed for the new 1/8" bone saddle. After final fitting of the saddle and pins and a set of Martin SP .012s, the LG 0 was ready for action. The end result was a clean vintage look like a wooden bridge LG and vastly improved tone and sustain. The tone was fuller and brighter with more volume. Another satisfied customer!
