There was no complaint about the advice inferred, I appreciate that you cannot know every guitar, and it does seem strange that my Standard LP has the wider bridge.
I only noticed it visually, it certainly wasn't obvious from the sound. The lower strings are a bit quiet, but that is due to the fact I cannot bet the pickup very close to the strings as the original gibson spring is too long and binds up before the pickup gets as high as I would like. I guess the gibson pickup bracket is somewhat further from the top of the pickup than the BKP one. Still, easy enough to fix, jut means I have to de-string the guitar.
The pickups sound great though, playing clean there is a much greater change from soft to hard picking than with the stock ones, and there seems to be more sustain too. The neck pickup sounds much sweeter and less muddy. I always hated the clean sound before, but now it is great.
The overdriven sound is good too, lots of bite but creamy too. Even at high gain settings I get no squeal from the unpotted pickups.
