I have a 1990's SR-400 and its fabulous. You can get a wider tonal range out of that instrument than any other instrument I've played. I find the SR-400's with active bass, mid and treble are best. I haven't enjoyed playing the ones that have only bass and treble controls. Doesn't cut it.
I actually ordered their circuit and pups for a custom instrument I built a while back. I highly recommend this bass if it has the bass, mid and treble EQ section.
Yes, it's the natural wood color, and it has 3 pickups, and four tone knobs.
