Hello again from GeetarGizmos.   We're very happy to offer our 2 1/8" hole spacing Bridge Backup Plate for acoustic guitar.  This spacing spacing is the most common for guitar bridges. The ideal fix for a bridge with worn-out pin holes. Or to just provide a rock solid backup for your current bridge. Significantly boosts the transfer of acoustic energy from the bridge to the soundboard. Purer tone, better projection.

Supplied with two-sided sticky tape - just press it in place.  Made from 1/16" thick brass plate, 2 5/8" long.  Shipped immediately with full USPS tracking.
