I can't show you the examples because they weren't on my bass. I didn't take photos of the work I saw. It never occurred to me to take pictures in the event that one day I might post an opinion on TB and receive a request for supporting evidence. By the way, I am not speaking of only one case. Now, I find it mildly offensive that anyone would assume that my comment was the result of "getting up on the wrong side of the bed" rather than the result of an honest and informed appraisal of what I saw. (Yes, Eric, I saw the smiley face.

) After 30 or so years, I know good work when I see it.
It's best for me not to name the individual or individuals on whose bass work was done but, in one case, we're not talking about some random unknown player. I'll leave it at that. With regard to the work itself, nothing that was done would necessarily detract from the overall playability or response of the bass. It simply did not reflect the level of pride that I would demand from someone working on my instrument.
The examples I saw involved work on bridge, fingerboard, nut, and body. I'll explain a couple in detail. When I look at the glue-joint where the fingerboard mates to the neck, I expect to see a ruler-straight, smooth joint. The example I saw was not. Because it was on the E side of the fingerboard, it didn't bother the player. He did, however, comment after looking at my bass that he wished it had been done like mine. A second example involved a nut that was not carved down or fared at the ends smoothly into the base of the pegbox. Again, nothing that would affect the playability or the sound, but a shortcut nonetheless and an ugly one at that.
I could go on, but I won't. I don't know which luthiers at Gage were responsible for the work I saw. The examples I saw fell far short of what would be expected from "the best luthiers anywhere." Note that that was the basis of my comment, that the work I've seen does not represent the best that can be reasonable expected. Examples of work I've seen from luthiers mentioned often in these threads reveal far superior craftsmanship and apparent pride.
So, now you know. Anyone can dump my experience and opinion into the barrel with the rest and decide for him/herself.
