Hi there, I have a 2011 Am Std Jazz bass that I keep wrestling with in terms of getting a tone I like and can use out of. I like the tone at home but in a band setting it either has too many mids and not enough bass or too much bass and not enough mids, although the Audere JZ3 drop-in plate installed has sorted most of that out. I've found the stock pickups to be lacking lows and a nice midrange. It has a great bite to it in the treble. Also, I'm not a fan of single coil hum. I've already had Dimarzio Model J's in there but I found them to be a bit too murky/lacking in treble. I used 500k pots but still didn't get the highs/bite I wanted. I'm wondering if the NJ4SE is more what I'm after; I'd like punchy lows, a growly midrange with some good treble bite. Quite an aggressive tone that would suit a rock mix but can be a little polite.
