This is the third yamaha bass that i bought in less than one year, my collection is composed by bb6, trb1006j and bb414.
This is the bass with best tone, that i have as passive bass, better than a warwick streamer standard first series, that was made in germany 20 years ago, fat humbucker and a single coil that sing, the best single coil i heard in 30+ year playing.
I like the sound powerfull on all pick up, the 2 pot 1 vol 1 tone + 1 switch probably is not flexible like 2 vol and 1 tone pot but i don't feel this lack.
I don't play it with flatwound strings, but i can't imagine it sound with flatwound string.
Today you can find it on used market a -50% or less, of the original price when in production, think about it instead Squire, Cort or some ibanez.
