Hey Greg, what 3 knob preamp have you tried with the Nordstand NJ P/U's that you like the best?
I'm wanting something that will still allow me to have a passive mode but I'm really missing the EQ capability of and active pre.
Have you tried the J-Retro or Aggie OBP-2?
What's the difference between the OBP-1 & 2? I've only installed the OBP1 & 3 in basses.
Thx!
I've got the OBP-1 in my Lull with the NJ5 single coils, and I absolutely love it.
The OBP-1 is boost only for both the treble and bass controls, while the OBP-2 is boost/cut on both. That leads lots of folks to add a passive tone control with the OBP-1 so that treble can be rolled off. I didn't do that on my Lull, and I can honestly say I don't miss it. I tend to boost both the bass & the treble about 25%, and cutting the treble back to 0 is all the rolloff I need.
The center frequencies are also a bit different:
OBP-1: 40 Hz (bass) and 4 kHz (treble)
OBP-2: 40 Hz (bass) and 6.5 kHz (treble)
I just received a set of Nordstrand Big Splits to put in my fretless, and I'm planning to also install an OBP-3 when I do the pickup swap (removing the Bart NTMB). I've tried my darndest to like the NTMB, but I just don't get along with it. I've yet to try the OBP-3, so we'll see how that goes.
I also just received a set of Nordstrand NJ5F pickups for King Koa. Depending on how my fretless experiment goes, I'll either put the OBP-1 or the OBP-3 in King Koa.
