Interesting. I did notice the Custom Shop has some in that range. Though I imagine they'd wind any non-infringing design wanted of course.
I'm thinking the '78 or a JB is for me. Just not sure which yet.
Fear with the JB is that it's too hot, and the '78 not hot enough, though I often wonder if the Seth would be fine, LOL!
Definitely have heard great tones out of all 3 though though. Naturally what you hook it too plays a role too. Guess I'm aiming for similar to what I had with an old Gibson V with factory p'ups tone wise, but JB sustain-wise.
I know that may seem contradictory, but the idea is to be able to switch from rhythm to lead without stomping on anything. The V was just a little short in the sustain department, otherwise I was happy with it.
That'd have been about a '73, so PAF type with A5, as best guess... so '78 seems like a fit, but a quick try of a Jackson Dinky with JB showed me the JB has awesome sustain... just not sure what to think about it's tone when turned down a bit, say for crunch or even further for finger picking.
