I'm building a bass with MM/J -pup configuration, and I'm going to aim for several different onboard sounds. There is a thing I can't figure out though. Can I connect a push-pull pot for one humbucker so that when pushed, I can roll from parallel (10) to single coil (0), and when pulled I can roll from series (10) to single coil (0)? I couldn't figure this out myself. I'm going to have the following modes available: 1) J <sweep> J + MM. 2) J + MM <sweep> MM. 3) J series with MM front coil (P-bass simulator). MM pickup switchable series-parallel-rear single coil in all of the above but the 3. What do You guys think, what would be the most intuitive way of connecting these modes? I was thinking about: -master volume. -master tone. -push-pull pot for the pickup balance (had this, I like it). -push-pull pot or 3-position switch for the MM mode selector. -2-pos switch for J series with MM front coil or normal. Any ideas? Thanks! -Aki.
