Been researching different models of Stick for about a year now, and finally ordered my NS/Stick this week.
The NS is different from the other Stick models in that it is designed from the beginning as a "multi mode" instrument.
The damper is disengageable so you can play it "touchstyle", or with traditional bass or guitar techniques.
It's also the only Stick with a guitar-type body.
Being a Ned Steinberger collaboration it has his well known headless design.
I don't know how many are out there, but they're an incredible instrument.
There have been a few revisions through the years,
and the current ones have either wenge wood or laminated bamboo necks with a different bevel on the back,
a dual-adjustable truss system and Emmett's Rails, instead of traditional frets.
Can't wait for mine to get here (likely early next week).
Best of luck with your search! www.stick.com www.stickist.com
