I've been doing a little set up work on my Bicen. Neck keeps wanting to bow a little. The more taught Fenders are no doubt adding more tension than the TIs that were on it. Anyway, I never really noticed before but when I have both PUs on the bass its louder. On all others if I add both PUs full on, the volume drops a little. Like all may basses with two PUs. (Neck PU is always more loud that both.) Is that just an odd thing with the sidewinders or my bass? Don't suppose anything would be wrong or needing attention. It sounds good, but just struck me as odd. Both PUs are always on full so never recall noticing it. (PUs are balanced height wise.)
