I'll lay odds the Greco will win.. Mine sounded amazing on arrival- so much better than my 74 4001.. The only reason I swapped out the pickups with a Horseshoe/ Toaster was to replicate a "Squire"..
Yeah same here, the Greco sounds hands down more Rick...
My 74 arrived with a seymour duncan in the rear (which is how it sounded haha!) and a hi gain neck which was okay. Replaced with Retrovibe hi gain copies, it sounds better but still not awesome. I'm tuned CGDA so there's a bit of wool on the low string but I set it all up with custom Newtones so maybe further experimentation required....
Greco completely awesome straight away. Might just swap the truss covers and be done with it!
