Now that the assorted holidays are over, I was finally able to give the one, B-Axis armed bass that was ready to play a good once over. Fair warning, though, I don't gig or play in live settings, so take all of this with a grain of salt. Different amps and/or settings might yield different results.
In other words, your mileage may vary.
First, some specs;
- Sixties-style Jazz body cut by Warmoth, solid alder construction, rear routed.
- Aerodyne Jazz neck.
- Tone Monster SEB2-ABPA+ preamp with a TBDV control pot. (18-volts, 2-band EQ + passive-only tone control, independent dual-volume pickup pot...yeah, I kinda went all-out on this one
)
- Rotosound 66 Swing Bass strings.
- And, of course, Bartolini B-Axis 4-string pickups.
I noodling around on it for a while, with no backing music or drum tracks, tweaking pickup volumes and tone/EQ settings as I went.
- It's fair to say they retain a lot of it's Jazzy "growl" in both modes, but with a good amount of bottom end. In other words, I'm happy with these noiseless Jazz pickups.
- Passive mode was quite usable. I would have no problem using these pickups in a passive-only bass.
- Active mode did bring out a little bit more "definition", for lack of a better word, when the EQ was set flat.
- With both pickups and passive tone at 100%, the active settings that were the most indistinguishable between the two was to turn both treble and bass down a slight amount. Call it -1, I guess? I'm pretty new to active basses, so sue me.

A funny thing I noticed about the Tone Monster preamp...the volume between modes are pretty much the same when the module's trim pot is set all the way down to zero. Since I wanted my active mode to have a little more
"sparkle" or
"oomph", I turned the pot up to somewhere between ⅛ to ¼ of a turn above zero.
