Hi, this is my first post here. I'm primarily a guitarist but I've got some gigs lined up where I'll be playing bass as well as acoustic and electric guitar. I have a Fender American Deluxe Jazz Bass, but I don't have a bass amp at the moment. It would lighten my load considerably if I could run both my bass and my acoustic guitar through a JBL 15" G2 cabinet instead of buying a real bass amp. What if I used an ART Tube MP as a direct box and went straight to the JBL? (I have an Aphex parametric EQ and could do some sound shaping with that for the bass too, if needed.) Or would it sound a lot better if I got a real bass amp? If so, what amp would you recommend? I'm playing mostly classic rock and blues. Thanks a lot!
