Why it sounds like that

Flea's studio bass on The Getaway is his Shell Pink '61 Jazz Bass. He got it from a fan and used it to record Stadium Arcadium and The Getaway. It has been his primary studio instrument since 2006, and he has recorded every record on it since he got it. He does not play it that much in big stadiums because of its old pickups. His 2016 signature Jazz Bass from Fender is a precise recreation of it.
