Besides the wonderful Jean Barault guitar that I purchased from Michael recently, I just acquired an older (I think 2004) but beautiful dark stained Gitane D-500 for use as a "travel-practice" guitar (I like to take a guitar along on family vacations but I don't always want to subject the Barault to the airlines' erratic policies on bringing guitars onboard).
I like the Gitane a lot but I feel that the tone could be brightened (it's very warm, but sort of flat) possibly by a "better" bridge" and feel that the guitar is worth the investment in a Dupont. I don't think the Gitane has its original bridge on it as its current bridge has compensated step ladder saddles, so clearly the previous owner experimented with bridges.
It's a nice bridge, and it makes the intonation spot on for sure, but it seems to have wooden shims under its feet (and there are extras in the case pocket) which gives me an action of about 2.4mm at the 12th fret of the low E-string and exactly the same for the high E. I think the neck has flat (0) relief though I'm not an expert at checking that. I guess that giving it some relief would raise the action height a little. However, the guitar doesn't buzz even at these low heights.
Anyway, I don't think that has as much to do with its flat tone. Of course, putting on new strings will help that a little I'm sure, but I think it needs more....
.....so primarily, my long-winded post is designed to get to the question: If I buy a Dupont bridge, does anyone have real-life experience with which size Dupont bridge to buy that might get me a string height of no more than 3.0mm, preferably around 2.8? Of course, it would be better to err on the side of starting out with slightly too much height than buying one that would get me too little height. I want to avoid using shims. I'd like it to start out as close to correct as possible.
If you have direct experience with putting a Dupont on a D-500, that would be great. If you have good general experience with these bridge issues, that's would be helpful too.
Thanks in advance.
