From what I gather, the meaning of a "mean sound" has totally changed over the years. In the 70s, it meant getting a Rick, lowering the action, turning off the bass and spamming treble. Nowdays, it means getting something like a Musicman, cutting highs slightly, and blasting mids. Who pioneered this sound? Was it Geddy with his Wal? Was it Flea with his Musicman Sabre?
