An Ibanez SoundGear bass came in with a set of active humbuckers the owner supplied, and cavities too small to take them. Both cavities were routed out to the new size, checked against each other, and the pickups fitted. Two hours, and the new cavities look factory.

What Came In
An Ibanez SoundGear bass and a pair of active humbuckers the owner had bought for it. The stock cavities were too small for the new pickups.
What We Found
The existing pickup cavities were smaller than the new pickups. Both had to be routed larger before anything could be fitted.
What We Did
Set the body up in a routing jig and routed both cavities out to the larger size. Confirmed the two were the same size and that the new pickups fit. The pickups themselves were the owner's. About two hours on the bench.

Result
The new cavities look factory, in Dave's words.
Can any pickup go in any bass?
Not without a look at the cavity first. Pickup shapes and sizes vary by maker, and a swap that needs the body cut has to be planned: a jig, a template, a route that ends up square and matched on both cavities. Done right it looks like the guitar shipped that way, which is the standard here.
