To start up I know the following facts : - Geddy's sound comes from his fingers - Other the his fingers, he uses a particular bass, and amp, studio setup, etc. that results into a specific sound. I know that ! And I do not seek to get the exact copy of his sound ! I just wonder which pedal could get me in the area of the sound heard in Moving pictures, the sort of Overdrive that breaks in, sometimes subtile, but that doesn't eat your lows. I already have a SansAmp RBI and a Bass Big Muff and I can't get that specific tone. Thanks !
