I know the SVT-CL is the all-around bass amp for any situation, but the V4B's weight would help me since I have to take the head and potential cab up 3 flights of stairs to store in my apartment. I don't think I'd mind the grind of the V4B (thinking about pairing it with the 212av or a 410hlf) but wondering if paired with a jazz bass... would it be too grindy to play outside of rock music? I play a lot of math-rock/emo/post-rock stuff but would also like to use my amp for playing neo-soul/jazz/funk stuff! If I could get a used SVT for the same price as a brand new or used V4B, should I just go with the SVT or will the V4B work for me in most situations (medium-sized gigs)? Also, what's maintenance costs like for both amps? I believe the V4B should be cheaper in maintenance because it has less tubes but if it's about the same cost at most shops, I might just consider going for an SVT.
