This might be a little left field for kit thinking but at the bottom of a Christmas ale, I found something to wondering about. What would happen if the saddle protruded through the bridge and soundboard and rested on the bridge plate? If there was a snug fit, wouldn’t this mean that there was more … “vibration”… through the sound board.

Maybe this has been tried before and it is most likely a question for Ken, John and those that have more knowledge of such things. Maybe it dampens the vibration…Maybe the strings pulling forward on the extreme saddle height would cause too much stress.

Food for thought? What do you think?

This is pretty much a guess --- but the bridge is like a distribution device for the string sound waves and the goal is to get the entire top vibrating, and at the same time the top, bracing and bridge are functioning to provide some balance for each string. I would think resting the saddle directly on the plate would change this design arrangement. Plus I would be concerned about losing the strength of ply effect provided by the bridge, top plate and bridge plate under the saddle. With that said I really don't know what would result!! I never tried it.

I would be very concerned that you would lose the strength that is obtained by the sandwiching effect that the bridge plate/top/bridge method gives now. If you think about it, you would be putting the entire torque on the bridge plate and I would be afraid that it would be a very short time before the glue joint would fail between the plate and the top. I also suspect that there would be a very large amount of sound dampening that would happen. The entire vibration transmission would be totally dependant on one glue line. I have given some thought however to something similar but I need to give it some more thought before I spill the beans.

As for the structural strength, it would be pretty easy to build a test bed to see what would happen. The sound testing however would take a bit more work as a guitar would need to be built for a good test to be obtained.

The old Gibson metal adjustable saddles (C**P) actually sat directly on the top in a hole (channel) cut completely through the bridge. And oh yeah -- some/many of those bridges were made of plastic!!

It seems to me that the saddle resting on the bridge plate would not be a good idea. The bridge plate isn't intended to be a transmitter of sound, and probably wouldn't be a good one. There's also the problem of the good contact between the bottom of the saddle and the surface it contacts. For the bottom of the standard saddle slot and the bottom of the saddle to be in "perfect" contact is a known necessity for best transmission of sound from the strings through the saddle to the bridge (to the top...). I would imagine it would be next to impossible to get such a perfect contact if you had to work all the way through a deep saddle slot and the top itself. And having done that, you'd still be transmitting sound to the plate, which is essentially a brace, instead of the top itself.

I agree with Bill -- saddle, bridge, bracing, plate, top work as a unit -- a perfect fit of the saddle is an essential basic requirement for quality sound production.
