I've read a bit about the pros and cons of different bridge designs which are typically used on classical instruments (violins, cellos, double bass etc). It seems most of the considerations were to do with the way in which strings cause the sound board to vibrate.
When I look at guitar bridges I'm left scratching my head. Obviously they work, they've been designed the way they have for centuries and they sound fine. People continually pay top dollar for them.
My question for those who understand guitar design and acoustic resonance is, why wouldn't acoustic or arch top guitars have a bridge like the ones on classical instruments?
