The only thing the bass knob does is turn down your gain from where you have it set. So whatever your gain is set at now...is exactly what you're getting. The knob just allows control.Another thing, the guy didnt connect the remote bass controller to my amp. When thats not connected doesnt it stay fixed at a maximum setting until i connect the bass controller and turn it down? Wouldnt my speakers have blown? Keep in mind that these solo barics have less than 2 hours of play. They are FAR from being broke in. Maybe thats what im waiting on to be satisfied with the sound??
