My main band is a blues/soul trio which I assumed would be P bass with flatwounds all the way.
Not so.
I use a Yamaha BB604 active bass with roundwounds. It’s a very loud bass which pushes my amp to the edge of distortion when you really dig in, or ease off for a really textured, chiming sort of warm rasp which really fills out the space in the trio format when needed.
Play softly near the neck with your fingers and it’s smooth, dig in with a pick by the bridge and it’s a full-throated roar.
It’s a wicked sound. If I have any sort of signature tone, it is accidentally that one.
