This is very nice, mute, fingered, pick, popped and slapped articulations are all available and you can easily setup your own velocity switch points. This is the only bass library I have that really seems to nail a "high up the neck" tone I am particularly fond of, this is controlled by the fretting position control.
There are plenty of presets and Greg has done a good job of getting some really nice tones form the Kontakt effects, of course you can also output clean to your favourite amp sim.
Edit - The above refers to the recently release flatwound precision bass for OTS, not this new J-Bass. DOH!
