So, we're talking about my favorite neck of all time, the bolt on Epi Tbird... I don't know about the newer versions, but mine is wide and on the chunky side, just how I like em.
When I pick my Epi EB0 after my Tbird, the first word coming to my mind is "broomstick", it really feels like a mandolin with chunkier frets...
The original Epi pups are indeed mud, and not in a good way, they are the equivalent of over-wound guitar pups, they are in the 14k range after all. They sound nice with (a lot of) distortion through.
I bought a pair of Gibson authority wrapped in glorious black plastic from a great man from Seattle sometime ago and I am a happy man since.
