Anyone know what the output is on that pickup?
Too new. If it's anything like a typical Gretsch Filtertron, it's fairly low output.
Found
this thread at a Gretsch forum, one post said they're supposed to be Fender copies of a TV Jones pickup.
Keep in mind that Gretsch owns the trademark on the name Filtertron and Fender doesn't actually own Gretsch, they just make and market them under license from Fred Gretsch. So it's no surprise that Fender came up with a new name.
