Ad says "Fishman Prefix preamp professionally added by previous owner."
But did that replace stock Guild electronics?
I bought the guitar. Haven't received it yet. As I understand it, these didn't come with electronics.
Somehow missed this the first time around.
Guild did use the "Prefix
Pro Blend" on the last generation of F65ce's, (used Prefixes on all of 'em) but they were Guild-labeled. I have one.
Don't think that version of it was actually available when that JF30 was built, so suspect you're right, added later.
But as you said in your NGD post, it's a nice unit.
And I agree, the .014-.056 would likely be too heavy for it, it probably shipped with .012-.053 pb lights.
Those might even let the top move a little more freely, besides lowereing stress on the neckset.
