My parts jazz is currently J/J with a good pair of Kent Armstrong pickups. But I've been wondering about something with an MM pickup again, but with series/parallel /single options to get back to something akin to J/J if required, although I rarely use that, typical just the neck J. But I noticed Wilkson makes what is pretty much half an MM bolted onto a J pickup. Has anyone tried that out and assessed how close to a true MM it can get? If I'm fiddling this much it then becomes tempting to swap the neck J out and put a P on there with series/parallel switching. There's space under the Pick guard to do this. By that point it wouldn't be much of a Jazz, and I'd have a spare pair of J pickups again.
