Do tell, passive/active a/b compared??
I don't quite understand the question, but here goes anyway. The preamp kept killing batteries, and the bass wouldn't make any noise when the battery died. And, the sound was incredibly scooped. It just wasn't quite the sound I like, and it wasn't ideal for a fretless bass. Not that the bass was fretless when I got it. It was a factory second that I got second hand as a "losing" ebay bid. Gotta love those. Anyway, the stock pickups were OK passive, I suppose, but I put Alumatones in a guitar I resurrected from the dead. They are like a cross between a P-90, a Fender single coil, and a very clean piezo in the guitar. I don't know how else to describe them. In the bass, they are extremely clear and they are also very sensitive to how close the are to the strings. If you raise them up next to the strings, they get aggressive and modern sounding. Lower them, and they get much more mellow. They will never be thumpy, but in a Thunderbird, thumpy isn't what you would expect anyway.
I play passive bass guitars. I don't need the competition.
