Hello Everyone, I have a Brand New Rickenbacker 4003 that I just got in the mail. My A string is WAY louder and sustains WAY longer than the other strings. This is for all notes up and down the string. The E string is comparitively whimpy. I've changed the strings from the stock ones to Daddario Chromes .45, checked the bridge, checked the nut, adjusted the pickup heights (no change). I have confirmed this problem playing thru different amps and also running the bass directly into a mixing board, recording the bass and visually observing the different amplitudes of the E and A strings. Does anyone have any solutions? Thanks very much in advance, its such a bummer to spend lots of money on something and then be disappointed like this.
