Not meaning to keep revisiting my own posts and milking them for all they're worth, but...
*FRAN*
I've found that with some tinkering it is possible to fit the claw with these pickups. It involves completely removing the baseplate for the magnets and putting the claw between the coil and the magnets. I think it's important to point out though that the magnets must be insulated against the claw while still in contact with the polepieces, and the claw needs its own ground connection. I'm still doing some juggling to get it right though. Like lots of things it seems there's one way in which it'll work fine and every other setup'll be full of problems. First off I didn't isolate the claw's ground, and it caused it to not be grounded properly. When I fixed that it developed a squeal not dissimilar to that of the CIJ pickups 😕
Although dispite the feedback squeal thing, it is noticably better shielded, so it'd be worth fixing it.
I'll keep tinkering with it and see if I can get it working properly, and if not, oh well, but I thought it would be worth mentioning if I do figure it out.
