This is in fact an Eminence bridge, it is a bit lower but the feet are angled and have to be fit. I think that I am the "others". There is a reference to the Eminence much earlier in this thread, post 380 on page 19, but it is only to ask why not use a 1/2 size bridge instead. That post refers to the Eminence as a "popular replacement" for the Stagg, but I don't believe there is any mention of anyone actually using one. The answer about the 1/2 size bridge vs the Eminence is that the arch is less than compatible on the 1/2 size. I can't explain in specific detail, but I had a long email conversation with the nice people at Gollihur who could. They even drew me pictures.. I'm sure I wore them out with my questions.
I had considered making a bridge from scratch, but my background is a kind of mashup of full orchestra/jazz band mixed with dirty smelly punk clubs. A sort of Mozart meets Mudhoney. As such, I am very much more acclimated to the whole diy modding of pawn shop gear. It's part of why I chose the Stagg to begin with.
I imagine that both the angle and the overstand will have to be altered considerably, and that is the next thing I plan to deal with when I get more time. I had not considered when I started all of this the potential of crushing those piezo cables as you have pointed out, but as you know I am also installing the magnetic pickup along with the bridge. I do also have some other options for a piezo that does not mount under the bridge feet, so I suppose I will just replace the stock piezo when/if the time comes. I don't feel like the stock pickup is garbage, and I don't really feel like it "needs" magnetic pickups either.. but as I mentioned before, it's all just sitting there anyway.. may as well put it to use.
