I've been meaning to post this one for a while. I know there's been a lot written about the 4003's bridge intonation strengths/weaknesses; if this has already been covered, my apologies (I didn't find anything like this in my Search tries).
This is how I created a tool to help me intonate my beloved 4003's. I'm not recommending this for anyone at all (it's actually not particularly safe), I'm just showing what's worked okay for me:
1) I started with a phillips-head screwdriver and a reasonably heavy-duty steel vice:
2) I mounted the screwdriver in the vice, clamped near the tip, and proceed to very carefully bend the screwdriver:
3) When I was done, it went okay, and the screwdriver looked like this:
4) See how it meets the space requirements to turn the bridge adjustment screws on my 4003:
5) The downside was a dimple on my steel vice:
Creating the tool helped me to intonate the 4003 with the strings still on, for just a few bucks; I hadn't found any other tools that would do that. If they are out there, perhaps someone could post them. My mapleglo '00 was acutally right on on 3 of the 4 strings, and just a little out on the other.
If nothing else you made it funner(or lack of a real word)
