It's the physics of vibrating string - the 'sweet spot' is the location that puts the 12th fret exactly half way between the bridge and the nut*, so that the open string and the note at 12 fret are an octave apart. The 50% ratio between vibrating length and musical octave is Pythagoras's eureeka discovery, I believe.mutepointe wrote:I didn't know mandolins have floating bridges. I don't own one. either. Here's my question, if an experienced person found the sweet spot for the bridge, couldn't this just be marked off? Would the sweet spot change over time or other variables like different weight strings or weather or the way a person played or the music that a person tended to play?

It's unbranded (no name or model whatsoever). All I know is that the seller bought it in Germany (he told me in an e-mail). I suspect it's a massproduced faux-mandolinMTGuru wrote:Oh, that's not good. So sorry. Can you tell us more about the instrument now - the name and model, and where it was made?
