I just got a new bridge for my mandolin from StewMac.
The old saddle was symmetrical( back, up, back, up) so no matter which way you flipped it didn't matter until you slotted it. This one is symmetrical except the first one or last one dependind which way you flip it is further back (foward). I need to know which side is the bass or treble side. I hope this makes sense. It's a compensated saddle.
