For 50% of my playing time I owned one bass, a 1968 Fender Precision.
For the other 50% I owned 2 basses. First a US Lakland 55-94 and a Wal mk3, and most recently a Sadowsky MV5 Metro Jazz and a Mike Lull PJ5.
ATM I'm checking out light weight basses to replace my Sadowsky. Currently a Cort GB35J, Lakland 55-02 and Ibanez EHB1505. I'll be back to 2 basses by the end of the Summer, when I've found the one.
