I asked luthier and bassist-around-town Karl Hoyt to install a set of K&K pups on a Michael Kelly Club Deluxe 5-string (E-C). This is such a vast improvement on what it sounded like before that I am kicking myself for not doing this earlier. With a set of Thomastik Jazz Flats on it, I have an amazingly flexible instrument: A great low end for jazz, Latin and folk, a really bright solo voice and in the middle of the neck it's well voiced for two- and three-note chords. Karl was right that the bass would sound much better, and as luck would have it, the K&K's work with the existing Fishman preamp. If you're dissatisfied with the peizo pup under the bridge of your present ABG, this is an experiment well worth trying, and it won't set you back a tremendous amount of cash.
