Great info. The biggest question is how do they sound?
I was afraid you'd ask that
I am primarily a guitarist with relatively little personal bass experience - ie. I don't really have anything to compare with, so read my comments with that in mind.
Note also that the strings are brand new D'Addario ProSteels (EPS170-5SL), as supplied by Warmoth.
The pickups are quiet, helped possibly by doing all the recommended shielding on the bass.
To me the sound is very clear and strong. There isn't the muddiness that seems to happen with some of the humbucker basses I have heard. Because I have wired the coils in parallel, there is not a big difference in the output when switching from single to dual coil mode. The tone fattens up a bit but retains clarity.
I will learn more about the tonal adjustments as I progress, but it seems to me that I can dial in a good range of tones from fat and bottom heavy to almost piano-like. This is exactly what I was after. The reason I went for these pickups was that the sales blurb suggested that they would give me, an inexperienced bass player, a large enough range of sounds to allow me to learn over time what tone and feel suits me and the music I play. The reason I listened to the sales blurb was that I have had good experience with Seymour Duncan products in the past.
There don't seem to be any obvious bright or dead spots over the fretboard, which is probably more of a comment on the instrument itself rather than any one component.
My verdict so far is that I really like the sound and have only good things to say about these pickups.
Sorry I can't give any comparisons with other instruments or pickups yet. I will get opinions from other bass players as well.
