Is your mandolin no longer sounding as bright and sparkling as it once did, or does it keep slipping out of tune? In the mandolin parts category, you'll find everything you need to get your instrument back into top condition, with the exception of mandolin strings. The tension of the eight strings puts certain components under considerable strain — the mandolin bridge in particular. As the bridge sits loosely on the soundboard, the wood and height adjusters absorb the brunt of that pressure. A new bridge can do wonders for your sustain and action. The tailpiece plays its part too: rattling cover plates and bent hooks will be a thing of the past once you opt for a solid replacement. Is tuning becoming increasingly difficult, or do the strings lose tension quickly? Then it may be time to look at your tuning machines. A set of smooth, reliable tuners will keep your mandolin perfectly in tune, no matter how hard you strike those double strings.
