pLEASE ...BEFORE YOU WOULD EVEN THINK OF SWAPPING....
anything new takes getting used to. Start over from scratch. reset your amps flat. Now...start by setting your pickup height. get the relationship of the 2 pickups correct to best suit your style. Dont be afraid to try many different settings. Ive actually had some neck pickups almost flush with the body, yet still got a good full tone from it. On my NYC 5...the front pickup is pretty low..it can be a little too hot.(and adding bass made it to over the top.) I like a good , solid note with no buzz and the B and E to be very clear, even and full. once I got this set correctly, adding just a touch of eq on the bass, it came alive. This bass is different from others youve tried. Its really about rethinking your approach. I assure you....if you do this...you will get what your looking for. Be patient. it may take time, but the rewards will be unreal.
VERY GOOD ADVICE HERE!! I had forgotten that on a lot of my basses I have had to adjust the PUP height a tad by dropping the Bass side or raising the treble side and it makes all the difference in the world!! I have done this on a LARGE percentage of my Sadowskys with excellent results!
