Anyone using this setup? I currently have the SPB3 and SJB3 in a MIJ Fender. I really like the bottom and top ends of the tone on these pickups, but I find the mids to be a bit thin. I thought that getting an Audere Z 4 band preamp with low and high mid control would help round out the middle, but I'm not sure if it is worth the investment. I am looking to see if anyone else on here has done this and what the results were. I love the bass, love the pickups for the most part and just want a little bit of control/boost in the mid range to finally dial in "the" tone in my head.
