I've decided on this pickup here, http://www.seymourduncan.com/products/bass-pickups/music-man/4string/smb4d_5d_cerami/ I'll be getting the 5 string model. It's going to be going in this bass here, http://www.lamusic.ca/AVALANCHE-5-STRING-Active-Bass-Guitar-p/avalanche5.htm I'm wondering what problems if any I'll run into. The pickups in my bass are active and there is a 3 band EQ on the bass. I know I'll have to cut into the body a bit as well, it's not a big deal. Thanks.
