I tried a bass with a set of Seymour Duncan active jazz pickups yesterday. I was round at my friend's (who's a very talented luthier), trying out a bass he had made and his Fodera Monarch. Of course the Fodera kicked butt (it was a standard Monarch with EMGs, Pope preamp, rosewood fingerboard, mahogany body and maple top). But the tone of the other bass (which had an alder body, maccassar ebony fingerboard, EMG parametric mid 3 band EQ, walnut top, and of course the aforementioned Seymour Duncan active jazz pickups) just sounded so much richer and fuller. Of course, I realise that there are some variables involved, which is why I printed the specs of both basses, but I can honestly say that I've never heard a better modern jazz sounding pickup. My friend told me that they are relatively new, but I was wondering if anyone else has experience with these. Comments would be much appreciated.
