Hi all, I have an early eighties Tokai Jazz Sound which I really like but would like to change the poor jazz pickup at the bridge. It is a slighly unusual Jazz Sound as it is a PJ config. I have no problems with the split P pickup but the jazz pup is anemic at best. What I would really like is a hot humbucker (stacked) that ideally is passive and fits into the existing space without the need to modify the bass. the dimensions of the j pup are 1.9 cm x 9.6cm / 0.7 inch x 3.7 inch. Anybody got any ideas please?
