Bruce estimates that 10% of the mandolins he receives for repair
have the bridge base flipped around- treble for bass.

If you notice a decline in tone/volume after a string change, check the bridge. If the base is flipped the bridge doesn’t fit well and sometimes can even cause a hum between the bridge base and the soundboard (top).

A simple precaution is to mark the bottom of the bridge base with a T and B when you take it off to ensure it goes back in the proper position.

Don’t hesitate to contact Bruce with any questions you may have and if your mandolin needs a ‘once over’ check out getting it MAC Inspected and joining the Mandolin Authority Club for discounts.
