hey all i'm thinking about upgrading the pickups in my Corvette $$. it has MM-style pickups in case you didn't know. i'm hearing great things about Bartolini and Nordstrand, and i would love to hear specific model recommendations, as well as any other brands you guys might like. my main concern is that the bass currently uses passive pickups and an active preamp, and I'm wondering what aftermarket stuff out there will accommodate this, as well as the various switching options that this bass offers (series, parallel, single, EQ bypass). in addition, i might be looking to upgrade the preamp as well. of course a common and well regarded choice would be the Aguilar OBP-2, and i was wondering if there are certain pickup brands or models which are known to work especially well with this preamp. THE WHOLE POINT: i'm really trying to get a tone that is more similar to michael manring's. the bass sounds pretty good right now, but it's too harsh. any advice on how to achieve this would be greatly appreciated!
