Some peeled and potted TB plus pups, note the production variations...........
The one on the bottom is an '89, the other from the mid-late 90's
For what you're doing it's difficult not to recommend some Lull pups, they are the exact same dimensions as you 60's Gibson, they even use the same mfg. for the chrome cover. Honestly they roar, far better than any of my 70's pups or the modern Gibson, here's one ready for installation on my BaCH
