Im currently in the process of getting one of my basses fully customised and i now have to consider what pickup configuration i want. The bass has a p-j configuration now but i dont really like it. I was wanting to switch it to soapbars but should i get one or two?? I was thinking of getting a Bartolini X-4 and a Bartolini M-3. I hate the way that two pickups cause frequency cancellations but i would like two pickups! What should i do????
