My guess is no. But I thought I'd ask. Ideas? I gots a bunch of strat singles I'm never really going to use, and I was thinking about making them into humbuckers like I saw Skullservant do somewhere on here
If you stacked them they'd be too deep for the guitar cavity most likely, and I'm not sure how the second pickup would react to the one on top of it since it would really just be a bar of metal on top of it (the back of the top pickup).
I did just find this picture though, so I guess it is possible? I guess you would just bolt it to the body instead of using the springs for pickup height? I dunno.
hmmm. Good point about the piece of metal in-between. Maybe there's a way to remove it? Shit, I don't know much about putting pickups together. All I know is that wiring two singles together in series seems pretty easy. And they are in no short supply up in here.
The only concern that I would see is that the baseplate of the back of the pickup is what has the connections/lead wires that go to the output. If you cut the back plate off you'd just have to be mindful of those connections and connect them from the pickup on top (the one with the base plate removed) to the one on the bottom.
Although looking at that picture it does seem like they kept the back plate on, sanded it down, and possibly just removed the magnets on the back, if there were magnets there.
