Nice knolling, but- and I'm sure you know- the materials and construction of that pickup aren't Bigsby at all. You gave a P90 some Bigsby cosmetics, it seems. Might sound just fine and pass as a Bigsby visually but it won't sound like the real thing. Yours is similar to how they built the pickups for the reissue Bigsby guitars that Gretsch came out with a while back.
Yep, but it actually sounds very close to the actual remakes, if Paul had access to the tools we have today I'm pretty sure he would be making them in a very similar way.
