"Educate me on why a bridge would be 2 piece please" Because someone has a lot of faith in glue and some scraps to make bridges out of? Notice that they called it an "interesting feature" Other people have made bridges built up from several pieces of wood so they may have some reasons for doing it that they feel make it a better construction. |

who drew this? Antes ? here is a ling to this style of bridge from the picture the 2nd piece was glued on top of the bottom. This bridge was a short lived design most were rectangular https://reverb.com/item/5067252-1930-s- ... l0-natural |

Didn't Kasha have a 2 piece bridge? |

Kasha's bridge design was two individual pieces designed to give some sort of (theoretical) impedance matching as I understand it. I believe what the drawing is showing is a bridge built up from two pieces of wood glued together (I could be wrong). |

Kasha originally meant for there to be an individual bridge for each string, which could be designed to optimize the response of each one by matching the impedance of the bridge/top with the string to enhance sound transmission from the string to the top. He compromised by splitting the bridge down the middle, between the D and G strings. This certainly change the way the bridge works, since a normal bridge is the heaviest brace, on the top, one of the stiffest, and goes right across the grain, unlike the other braces in the lower bout. At any rate, the idea of an 'impedance matching' bridge is somewhat odd, since the function the bridge is to define the string length by presenting it with a fairly large mismatch in impedance. When Kasha came up with his ideas little was known about how the guitar actually worked, and his ideas seemed about as good as anybody's. We've learned some stuff since then. |

It would probably be more split resistant. I think I remembered Gore or somebody doing it with the thin piece of carbon fiber in the middle to make it more rigid. Pat |

Trevor Gore uses a three horizontally laminated bridge structure with CF mat between to make a very stiff bridge on his falcate braced SS guitars to provide across the width stiffness since he has no braces crossing the centre line of the top. I can't actually see what is intended in the drawing you show. Dave |
