Ok, I've read many of the threads on both the Am. Dlx 5 as well as the RB5. Being two totally different animals,(Am Dlx is active and the RB is passive) which will serve me better as I play mostly contemporary gospel and jazz. I know that the active basses are great for the "modern" tone that I need. But I really like the B string on the RB5, although it is not as hi-fi as I would like for it to be. I have a Ken Smith BSRJ5 and a Fender Am. Dlx 4. Just bought the RB5 but might trade it for the Am. Dlx 5.
