Re: Jaguar Humbuckers
Tell you what might work, the Stag Mag.
By definition, the single coil sounds will be authentic precisely because they are single coils. The downside of this suggestion is that, without the screening "claw", the single coil sounds would be more Mustang than Jaguar.
Another possibility would be P-Rails. They would need to be installed the wrong way about to get the Rail coils where the Jag coils would normally be. Doing that would mess up the P90 sounds.
