OK, so I am having Cliff Bordwell build me a new 4 string Ball Bass. I currently have Aero Type 1 J's scheduled for installation. My rational is that if I ever want to change tone, J's are an easy format with lots of options. Well here is my problem. I already have a vintage sounding bass with my Darkstar loaded P-bass. So, I am thinking about doing a more modern sound. I had a Stingray, loved the tone, hated the neck (I like J-shapes, sorry), and the true-oil finish didn't work for me as my hands sweat when I play. Also, I hated how the notes were very unbalanced from string to string and throughout the neck. But, like I said, I loved the tone, and have heard that many aftermarket MM pickups are more balanced. Thus, I am thinking about installing one or two Music Man style pickups in the bass. I did have a Warmoth DIYer that I built a couple of years ago - I tried both the Alnico and the Ceramic Duncan MM pickups in it and preferred the ceramics - tighter bottom. The bass Cliff is building for me has a Swamp Ash Body, Flamed Maple top, Maple Neck with a Maple Board. So, the question is: 1) Do I stay with the Aero Jazz Pickups 2) Go with one MM pickup 3) Go with Two MM pickups Also, if I go with the MM pickups, which one? I was thinking about a nordstand quad coil - looking for that ultra clear, Wal sound. Any advise would be great.
