I will change the electronics. My original pickup is duncan custom jazz pickup~ and pre-amp is Bartolini NTMB. I'm looking for Sadowsky Humcan-celling or Nordstrand single NJ5. How do you think about Sadowsky Humcan-celling + Bartolini NTMB electronics? Is that good mix? Or Nordy NJ5 + NTMB Is better? if the NTMB is worst, I have a plan that change the pre-amp. OBP-3 or Sadowsky VTC Preamp. my bass's spec is.. Swamp Ash body, Graphite Reinforced Maple Neck and Flame maple fretboard. Mike lull's M5V Bass.
