OK, I know this gets into active vs passive, onboard vs outboard, etc. but I'm not trying to start a religious debate here. I'm going to order a Lakland Darryl Jones because I want a Jazz style bass and I dig the bound neck and block inlays that give it that vintage vibe. I'm going to run it through a BBE B-Max. We play rock covers from 60's to 00's (heavy on 70's) with some Motown, Funk, Pop Punk, and Country thrown in. I'm asking about the J-Retro because it really needs to be factory installed on this bass. I play an active bass now but I don't tend to fiddle too much with the tone onstage. I do like to make it a bit brighter for slap and get it mellow and thick for country and slow rock. I've heard great things about the J-Retro and I worry that I'll miss it if I don't order it that way. But then I could use the money for something else. Oh, the pain of making a decision! Do you think that the J-Retro will... 1) complement the B-Max+Aguilar? 2) hold the value of the Darryl Jones if I trade it in a couple years? I'd love to just try two DJ's side-by-side with and without the J-Retro but I don't have that luxury. I will get a chance to play the passive version again tomorrow though Man, I love this bass!
