And that is exactly why the thought these had the standard LP Rec pups in them (this is one, I would wager); I remember that thread now.
This one here is not the same pickup though (and the colour of the epoxy is the least significant of the differences ;P). Interesting transition between the original pickup and the eventual square one (nevermind the Epi JC Sig which, again, looks the same as the LP Sig but I doubt is on the inside). ... in fact, I could not see this before, but that small rectangular impression there in the second pic (that I can now see on my monitor at home) seems curiously similar in size/shape to the bobbins for the G3/S1 pickups (the LP Rec pups had ovular bobbins whose flanges were sized to fit those covers better - we've seen those NOS on ebay and they often poke out of the epoxy a bit in bits; the white epoxy one is one of the cleanest I have seen aside from Les's original prototypes which have no covers, I doubt it was mass produced in the same way; could be the only one )... and the square LP Sig pup was a Bill Lawrence design you say (just like the G3/S1)... maybe a single coil after all. Really curious about DCR now.
The only similarities between LP Rec and G3/S1 pups I know of: blade pole pieces and used on both guitar as well as bass models (and they didn't suck in either application).
