Ok, after reading a few posts, I think some people (myself included) are a little confused as to what this does exactly. I think the wording in the manual makes it confusing, along with the fact that both the remote bass control and the bass boost on the amp itself is set from 0db-18db, which leads people to think they are controlling the same thing. If I'm wrong, please correct me. From what I can tell, the bass boost is just that. It boosts the bass at a certain frequency (best to just leave it at 0db). The remote bass control on the other hand alters the gain setting. AND, it doesn't actually boost or raise anything. Instead, at its max setting of 18db, it doesn't alter anything, and as you dial it down to 0db, it lowers the gain setting. Is this correct? I'm assuming this, because if you plug in the controller with it set at 18db, there's no difference compared to having it unplugged. Did this make any sense? If anyone knows more, please correct me. Thanks!
