I'm considering purchasing a Carvin Bass Rig the RL1018 which you can scope out at their website -after being impressed with the price and features, my only concern is in their catalog they show the frequency response chart which as it nears my Low B string's 30 Hz seems like maybe it won't push those low frequencies all that terribly well. I don't have the catalogue in front of me at the moment but I recall drop-off was looking like an issue at 50Hz. my question is if I buy this rig and plug my 6 string Bass into into it, how will the open low B-string sound? is there a better head for low end? (probably not this cheap I bet). I used to use a GK800RB but it blew up on me as I've heard they do, GK replaced literally eerything inside the chassis and it blew again, so I'm off GK's forever. also I really think I need 1,000W at this point in my career. I'm currently using an old Kustom Keyboard amp & Cab becasue it's all I have. someone help me!
