I have a 2006 US Deluxe J 5. SCR pickups and active preamp. I'm not much of a guy to dick with settings, and I love how the bass sounds with all the controls flat, with minimal tweaking depending on the venue. However on the weekend I decided to play with the settings, and in particular see what sounds the different pickups gave. bridge pickup had typical tone - throaty, burpy and aggressive. Cool. Not the sort of sound I usually need but when blended with neck pickup gives me the sound I need. No hint of hum either! When I solo the neck pickup though out jumps this robust P style sound that surpirised me. Again big, muscular and aggressive but with the thump that I was after. Really wasn't expecting this but the most surprising thing is with either pickup solo'd, the output increased noticeably from when they are blended 50/50. Is this normal? I'm certainly not worried about it. The new tones I get are exiting and sound great. Does the same happen for passive basses, as thats what my next bass will be I think.
