Ready for your guitar from the Margasa family of instruments and parts we have 3 sets of bridge pins for acoustic guitars. 1 set of brass, 1 set of chrome, 1 set of ebony with abalone dots. The brass and chrome pins are heat treated for more sustain and better overall tone. Each pin is hand engraved with a Margasa signature and comes in a holding block made from recycled mahogany. This looks fantastic for retail or repair shop display cases and counters. Or use to keep neatly at your home work bench. See photos, also available in individual sets. All of these are a major upgrade from stock plastic bridge pins and an easy, inexpensive way to greatly improve the tone of your acoustic guitar.
