After reading x amount of posts about the mojo of the Sadowsky Pre/DI, I've been thinking about getting one to help a bit with the clean tone for my passive basses. Just to see what it can add/produce to the tone and to see what all the fuss is about (perhaps i'll hear that mojo). I already own a Radial Bassbone which is pretty cool since I can plug both passive basses into and have them eq'd a bit differently and that takes care of the DI. I own an Aggie AG500 and an Aggie DB750 for amps and I've quite happy with both of them. He's my question... Given the fact that I have the Radial Bassbone, and the fact that the AG500 and the DB750 have the same EQ points as the Sadowsky Pre/DI for the (40hz for Bass and 4Khz for Treble). I'm not unhappy with my tone, just (like many of us) curious as to if I could make a good thing even better. PS. I've owned a Sadowsky in the past Metro RV-5. Very impressed with the bass, but the pre-amp actually didn't really speak to me in that bass. However I'm not stranger to admiting i'm wrong and re-evaluating things and loving it the 2nd time around. So my idea is that the outboard could work really well with either the JO5 of DJ5.
