im a big fan of yamaha there basses are always well made but i never had one i have kept hold of
i had a yamaha attitude plus, rbx200 fretless, attitude special and they were nice to play just wasnt overly impressed soundwise
i own ibanez sr505 and an old roadster rs900 and i love the sound of these ,so for me its ibanez but to be honest i would say that both companies both have good quality contol
