The problem was the bone saddle. It had different densities in it, it was visible in front of a light with a magnifying glass. the suspicious area was more translucent and therefore less dense. I have since cut a new one and now it works great.

I have plenty of balls, I just have no need for that useless nonsense. I dont miss High School antics. I am really too busy to be on this computer wasting time. I am becoming a slave to this forum. The real world is more important.

I think VP is correct here, especially since replacing the saddle corrected the problem. Bone is grown by ignorant animals under uncontrolled conditions, and variations in density (heterogeneity) can occur.

He is far from correct
Re-read what he said and then explain how piezo elements work and how inconsistent density is going to effect the output of both a single string and then others adjacent to it.
Then explain how the timber on which it is resting doesn't play a far greater role in your conclusions seeing as how it has inherently far more inconsistency in it's physical and mechanical properties than than the bone that is adjacent to it. and also touching the piezo element.
Then explain and demonstrate how the speed of sound varies in bone and is related to it's amplitude at the frequencies at various densities and show how that impacts on the way in which a piezo element generates a signal.
You can use practical scientific examples of your research to back it up as it would probably reflect mine. Once you have done that you can conclude that his diagnosis of the fault was bullshit and if he actually fixed it was the result of a fortuitous and simple coincidence.,.
It is funny though, when I swapped it end for end the weak spot was now under the A and D strings. Let me recap: Originally it was the B and G strings that were weak. I refiled the saddle, perfectly flat, no change. The I turned the saddle around, end to end. Guess what? Now the A and the D strings were weak. Conclusion: Weak spot in saddle. Outcome: Happy customer with a refitted saddle. Have a nice day!

Congratulations. You have just re-written physics.
You really don't have a clue what you are talking about. Give it up.
Glad to hear that the saddle density (which directly couples the string's energy to the bridge/soundboard) doesn't have a significant effect on sound quality. I'll be able to start using cardboard or sponge for my saddles and nuts.He is far from correct

Here's an experiment. Make a saddle consisting of two pieces - one bone and one plastic, each under three of the strings. Pluck each string and record. Then switch the two saddle pieces to the opposite strings and repeat. Compare spectral analyses.
If there are no differences, then I will believe that saddle density has no effect on the sound. Until then, this is the internet and I can believe anything I want.![]()

I interpret your statement as saying that saddle density doesn't affect the output of a string (that is, the energy transmitted from the string to the underlying structures.)... explain ... how inconsistent density is going to effect the output of both a single string and then others adjacent to it.

If you'd read it correctly along with the rest of the thread you would take it to mean that natural variations in the bone density of the saddle do not effect the output of the piezo transducer.
Nobody has even suggested that different materials do not effect the timbre of an instrument.
The fact that a bone saddle is rigid with near identical elastic properties is all that is important when it is set on a piezo transducer. Variations in material density within the bone make absolutely no difference unless you have ridiculous extremes in that density. Of the hundreds of transducer saddles I have worked on over the years I have yet to come across one that will not give an even response across the strings if fitted correctly with a prefect fit along the bottom of the saddle slot and perfectly upright with the correct break angle or string ramp. You can of course believe what you like.
I am working on another bone saddle for a guitar with no piezo element. I was curious to try the bad saddle. It is not as obvoius as with the piezo, but an audible difference is apparent. Upon examining the bad saddle with another new one, the difference is quite obvious, The new one is not anywhere near as translucent as the bad one.

As I have pointed out to you in the past, I teach this shit at graduate and post graduate level. If you'd like to dig up the old threads where I pointed out you were wrong I'd be happy to explain it again.mutley I am beginning wonder if you even know the definition of the word density and why us Americans associate it with the elements of sustainability in a guitar because I have used the term and every time I have associated this word with its relevance to pretty much what is discussed here you jump on board and tell me how wrong I am about what I said and I have no Idea what i am talking about which is an insult to my inelegance because dense / hard materials does have a direct effect on sustain whether you agree or not does not change that fact.
That Is All
Carry On.
