Well, it's kind of a mixed bag. You have much more control at your fingertips with all the extra knobs, but that in turn makes it more complicated to dial in the exact tone you're looking for. While I appreciate all the tonal possibilities, all those controls can be daunting. The blend control in particular makes repeatability of dialing in a desired sound after switching around the controls difficult. You either have to set it and forget it or be prepared to constantly fiddle around on the fly while you're playing. I can only imagine what a Series instrument is like! Add a SF-2 Superfilter and you've really need to be an Electrical Engineer to set the thing (I am an EE, and I can't handle that many controls, LOL!). In summation, I guess everything in life is a compromise, so there you have it.
Timothy B. Schmitt of the Eagles has his basses (Carvin) set up with passive J's and a single volume pot. He claims that he wants all his tone shaping to be done outboard (at his amp). While I wouldn't want that myself, there is a certain wisdom in economy. To be fair, TBS doesn't have to change his tone very often, LOL!
This bass is by far the most complicated instrument I own. In fact, as I am primarily a Fender player (mostly guitar, but bass also), my other instruments have simple passive controls. They are also nowhere near as versatile as that Alembic is though. I went the other way with the Alembic only because I wanted a Swiss Army Knife of basses. I got that, but it takes a lot of fiddling to find your desired sound. Eschewing the Bass/Treble or Q/Filter controls would have simplified things, but they would have also seriously curtailed the tonal possibilities.
Personally, I set my Eden WT-550 head up with basically flat EQ. I do the tone shaping right from the bass depending on the song, style, room characteristics and mood/preference. Try that with a Fender J, LOL!
