The left channel is the older recording, the right channel is the fully modified bridge.

Interesting - did you happen to take any before and after clips? The theory says that the reason a spider, and to a lesser extent, a tricone have longer attack and sustain than a biscuit is due to the fact that they do have more mass - once you get that bridge moving it tends to stay in motion. It would seem like reducing mass would shorten attack and sustain.


I'm not sure about the mass is better Freeman. Any tricone will have a lot more mass than a biscuit, and National bridges are fairly paired down.
I reasoned that:
It takes energy to move mass. The more mass you have then the more energy it takes to move it the same amount. i.e. The heavier your bridge then the harder you have to vibrate the string to get it to move, and not forgetting that it has to accelerate in one direction, then stop and move in the other.
Also after some investigation it seems that National scalloped their bridges to give more flexibility and improve bass response. Perhaps this is where the energy is stored for the sustain? I really don't know, and am only guessing, (and of course copying!).

That is about as technical as I am ever likely to get I'm afraid. :(

'Fraid not Jake. I did a half hearted mod about 6 months ago. Since then it's been work,work, work. Trouble is that you have to mike the guitar and it would be impossible (for me) to get exactly the same set-up. I know it is more fun to play now, and that's good enough. :D

If you did take clips, particularly of individual strings, you can look at both the time domain and frequency domain with a program like Audacity - time domain will show you changes in both volume and sustain, frequency will show if there are more or less partials (ie complexity) in the note.

I once saw a discussion that said John Dopyera experimented with different saddle materials include brass before determining that maple or ebony capped maple sounded best - I always thought that had to do with mass.

A bit of both Jake, I started off reducing the mass but kept the profiles tapering to guard against sympathetic vibration. Then I saw the Nationals with the scalloped ends. Must have taken 20% of the mass off.

Though I'm happy with the guitar I felt it lacked volume, sustain and needed opening up a little. I spoke to Len and he said that the very early bridges were a "little chunky". So I've filed mine down. Here are some pics of the finished bridge:

First I removed a fair bit of metal with a file. The bulk of it came off the bass side. This had a noticeable effect on the 6th (D) string and a less pronounced effect on the others. So off it came again and I balanced it out and scalloped the ends of the arms.

That did the trick. More volume and sustain I've also noticed it sounds a lot less damped when fretting now, the fretted sound is a lot closer to the static slide sound.
A useful mod for the lower priced Tricones out there. Thought I'd share it with you. :D
