The most cost-effective idea isn't always the best one, that is for sure.
Gibson used Alnico 5 in the original and even though the wind with the coils isn't the same in these Epi Newports, using the same grade of Alnico magnet puts the sound back in the ballpark and also solves the excessive string pull and intonation issues that many have experienced. I tried a 4 different Alnico 5 bar mags across my two favorite companies, unoriented as well as polished and roughcast types, and 2 different lengths in there as well: a certain suppliers A5 won and I'm sticking with it.
Because I actually care and because I can, I went a bit further with the mod recently and rethreaded the internal steel parts to convert them to USA Imperial because the stock pickup pole screws are metric M3 mystery steel, different than the real parts, and I didn't trust it. I swapped 5 different screw steel grades from 1008-1022 and figured that out as well. Excellent and deliciously toneful results.
Just for kicks, I ordered one of the Allparts replacements and they are exactly the same pickup. If any of you are thinking of getting one as some "upgrade", you will be wasting your money. Don't do that.
500k V/V/T, first a .022uF cap but now a .033uF for a bit more range with the darker sounds as needed.
