Now the real question is whatever happened to Guild branded guitar strings? I think they died when they closed the Westerly plant.
No, they were carried over into Corona but Fender switched from D'Addario to their own Squier in-house Mexican factory and changed the "G" to an .024, and then dropped Guild-branded strings in Tacoma.
Tacoma spec sheets showed the .025 (D'A) G in the Guild L350 string set for a couple of years after the switch, while packaging reflected the .024's.
In fact it was that change to the .024 that led me to look for a single PB .025, and discover that D'A EJ-16's were the same as the original L350's except for that .025G had to buy a single. But alloy color matched an old set of L350 I'd stashed, and was "redder" than the Squier sets. Been buyin' 'em that way ever since, except for experiments with S&S and Silk & Bronze.
They brought back D'Addario in New Hartford, going to coated medium PB as the factory spec gauge, and even introducing a "balanced tension set". Dropped when NH closed. Doubt D'A'll talk to 'em about any more private branding, what's the point?
