I hope this hasn't been covered... I did a search but didn't see any posts which address my observations. I have an SX SPJ-62 (a P/J Fender clone, for those who don't know) and the volume decreases when I have both pickups on full. When I solo the P pickup, it's noticably louder, and somewhat more articulate. I like the fundamental concept of a P/J configuration, but the array on the SX seems a little cloudy... the tone lacks a little definition as compared to the P soloed and the output dips. Is this standard for all or most P/J combos, or should I think about upgrading one or both pickups? I look forward to those of you with more electronics savvy enlightening me on this matter!
