Hi,
I got this luthier living pretty close to me. He sells pickups too. it's Johnny Mørch. He's always been about quality without compromise.
he writes this about his fat fingers pickups:
This popular pickup is designed for bass players who wants considerably higher outputs and a more gutsy and full tone with a warmer, fuller sound quality to the lower midrange and a big, open bass response. The treble has a certain “vintage” characteristic – i.e. with a gradual treble roll off as opposed to super penetrating highs.
there are several others. and there is a page with a full arsenal of a simple bassline played on the different pickups in the same bass ( it's a test bass he has where you can slide different pickups in and out with out soldering. pretty neat if you ask me. )
anyways. I vouch for all his products. Nothing in this luthier's workshop is less than awesome. take a look in the gallery too. He's been doing this job, or should I say passion, for his whole life. I've played boutique before, but nothing like his instruments/pickups/electronics. Each instrument I've played made by Mørch has been 7th heaven in regards of playability and a true work of art.
have a look at his pickups here:
