I'm building a jazzmaster and I want to put a p-90 and mini humbucker on it. I'm avoiding the top rhythm circuit and was originally going just to have a tone each, master volume and a three way switch. But I've just read on another forum about the volume differences and hum from the p-90 so I was wondering if anyone knew whether a separate volume and tone would be necessary much like on a LP.

Any tips about anything I've said would be very well received.

Thanks guys,
