Mincer,
My 1980 ES-335 (with a Maple neck) had a set of '59s. The bridge was perfectly fine, but I seemed to find myself twiddling often with the amp's and Guitar's knobs whenever I used the neck P/U. It was rather "boomy". Mr. Duncan claims his SH-1 '59 is as direct a copy of Beck's '59 Les Paul P/U's as can be mass produced. I accept that; I've no doubt that even Halle Berry has bad breath first thing in the morning! I tried a DiMarzio Air Classic in the neck and wound up spending significantly less time twiddling with my knobs as a result; substantial improvement. Not to worry: Duncan's vintage soapbars are fantastic!
