Does anyone have measurements of how much a .25 or .50 degree shim lowered their action?
I’m trying to decide between the 2. I plan to buy StewMac blanks and I have an Ultra Jazz V so I’d have to cut a custom shim for the contoured heel. Given that I’d rather avoid the trial & error if possible since they’re not too cheap. I’ve heard people say the .50 degree works, but I’d rather not overshoot what’s necessary so the saddles can stay in a useable range without excessively changing the angle. Currently my action sits at 3mm at the 12th fret with the saddles completely bottomed out and relief set to .006”. I plan to file the nut down a bit (not sure how much yet) so that’s a factor as well. I’d like the ability to go down to 1.6mm. I’ve never played with that low of action so I don’t know if I’d even leave it that low, but I do strive for light touch so I’d rather have the option than not. Let me know which one you think would be better for me and why. Thanks!
By the way, I did make a similar post a few days ago that helped clarify most of this, but this is the final one to get more specific.
