I read recently that the RBI loses its lowend at lower volume levels. Now I've only played my RBI at band practice and use a combo for home practice, so I've never experienced this, but that comment got me thinking. Maybe its the level setting that would cause this? lets try turning the poweramp down and turn the level on the RBI up? what happens? If no power amp volume, then how about cranking the RBI with your bass volume at a lower level. Hear any difference? My past experience has been to try and match the volume level when the RBI is active, with the RBI active switch disengaged. To me, that setting would be 0 gain correct? Are any other of you RBI users tinkering with the level in any other ways ?
