Seeing one of these for sale with Bass Direct, I idly clicked on the demo video....
....not really expecting to hear much I liked, as neither bass humbuckers, nor pickups in combination usually do much for me.
But I really like the sound of these, nicely full and warm, well balanced for my taste. Fano call them Fanobird pickups. (I found an opinion somewhere that they aren't as bass-centric as Thunderbird pickups, does that sound right?)
Demoing starts at 3'00", with both on full at first. I especially enjoyed the neck full / bridge half at 3'25".
(The moment just before that, when he slowly turns down the bridge volume with the strings still ringing, and the scoop gets filled in.... lovely 😁 )
