I've spent a lot of years playing active basses but my taste is changing to favor passive basses these days (especially in studio). I was in a music store recently and took my 62 RI Jazz bass and my Metro 5. I A/B'd my Metro against my 62 RI (running the 62 RI thru a Sadowsky outboard pre). My ears heard no difference. If anything, my 62 RI may have had a bit more clarity because of the single coil pickups I guess. I'm in the process of looking for a good outboard preamp to use in conjunction with my passive basses for when I want to add that flavor. Any suggestions?
