I'd say the 55-02 as well. Much more tonal options and better pre-amp. I own a 55-01 and a Joe Osborn 5. Having said that, I had a 55-02 first and didn't feel comfortable with it due to the pickup placing. On a Jazz bass, I like to play in between the 2 pickups. On the 55-02, if I played just below the jazz pickup, the strings felt to rubbery. If I played over the MM pickup, the strings felt too stiff. I ended up trading it for the JO5 which is a better fit for me. I'm just a Jazz bass junkie!
