I have a Fender Jazz that I can not intonate the E string. All other strings are fine. The E saddle is pushed all the way forward, and still get a flat reading. I use 45-100. Fender's spec, for this bass, is 45-105. Would switching to a 105 really make a difference? What's the reason that Fender recommends 45-105 over 45-100? Thanks.
