Fitting Jazzmaster pups in place of humbuckers

Ok, In a nutshell I have a pair of hot jazzes that I bought a few years ago intending to fit them to a LP copy. Partly cos I like chunky SCs, and partly cos I wanted to be different.

Now it's a couple of years later and my guitar life is getting back on the road after life got in the way.

I've had the things out of the boxes, and I'm amazed at how exactly they're the same size as a HB mount ring. There goes plan 1.

The take off points for the wiring are pretty much exactly under two of the 4 mount ring->body screw holes. There goes plan 2 of a simple shave down.

It's worth noting that the coil winding barely comes halfway across the width of the bobbin. I assume Fender had a reason for making the thing so big, but certainly as wound by SD there's a lot of wasted bobbin material there, making me think that a cutdown might be possible.

What worries me is moving the take-off points. I've modded regular Gibson HBs for 4-core wire before, so don't mind getting physical with a pickup, but I don't like the look of that pickup wire going to the take-off. It looks like my soldering iron might just melt it.

My ideal plan would be to trim the top of the bobbin to clear the inside of the mount ring and similar to the bottom, leaving a couple of lugs to mount regular HB fitting screws and springs thru; and move the takeoff pints inboard 5mil or so to accomodate.

How much does this sound like a disaster in the making, and can anyone comment on soldering pickup wire? Especially info like iron wattage and any non-standard solder wire etc...

:)

Has anyone else attempted such a fitting?

That was the whole point, really.

I don't think I actually want a Jazzmaster. Ones worth having tend to sell for stupid money, and I don't want to have to be worried it was expensive when I start using it. For me it takes all the fun out of it, just like when a new guitar is still perfect and has't picked up it's first dings.

I do want some chunky single coils on a Gibson neck though, and when I started this (ie, bought the pickups) P90s hadn't really come back into fashion, or I might have just gone with them for an easy life. Or not: the JM's were a particularly good deal, and I'm a tightwad at times. Having bought them I'm not going to give up completely, although I might end up just building a tele or something quick and easy and whacking them on that with the original style mounts and either using HB size 90's on the LP.

Basically it can be summarised as 'sounded like a good idea at the time'...

I'm taking care of the excess size by removing it. I'm going to take a cutting tool to the pickup bobbin to make it fit.

There's a huge overhang on the top/bottom of the bobbin relative to the actual width of the winding. Plenty of scope to get it into a standard HB mount. I reckon if it might even be possible to get it into a mini-HB hole, but that doesn't interest me.

I can think of several possible schemes, a couple of which are in the OP, I wondered if anyone else had tried it so that I could benefit from their experience. If anyone is actually interested, I'll report back in a bit (maybe a couple of weeks) when I've done it.

The other point about the fragility of the winding wire (I'll need to move the take-offs) has been answered by some searching in the Pickup Lounge. (here) among others.
