So, I have a Euro 4LX. Many of you might remember it because of the sunburst refinish. I also switched it to black hardware and an EMG BTS preamp. I must admit that I find myself unhappy with the tone in comparison to my US NS4. Now for starters, I realize that comparing the basses is not apples to apples. The NS4 has the humbuckers, 18 volt preamp and is a walnut back/buckeye top. Just the wood alone is a big difference of course. However, I can't help but wonder if a switch to one of the US preamps that Spector sells wouldn't get it closer.
My question is that I love the sound of my NS4. More growl, more low end, more punch, etc. Anyway, I see the 9 volt preamp comes with the PJ models (not to mention is pricier). If i love the NS4, is the 18 volt a better option, or is their something about the pairing of the 18 volt with the humbuckers vs the 9 volt with the PJ? Any thoughts are greatly appreciated.
