Hi; I've recently decided to add a pickup to my bass. The current pickup on my bass is a status(kent armstrong) single coil+phantom coil soapbar; and i will buy and install a Bartolini CB triple coil pickup next to it. And then i'll install a 3-way coil tap for the bartolini and a noll electronics 4 band preamp. I guess these pickups have different output levels; so my questions are: 1- will this cause me a big problem if the output levels are different from eachother? 2- is there a way to "equalize" or level out the output levels before the preamp and the pan pot. thanks.
