Potentiometer with indexing.

Mouser - http://www.mouser.com has some pots with 11 'detents'. 313-3000-1K (linear 1K), 313-4000-1K (audio 1K) - other values available.

Tolerance of resistance 20-30%, and you'll not get a presice, repeatable resistance change for each step.

Oh, WOW
That's a great site.
They have some damn interesting gear.
That pot looks like EXACTLY what I'm looking for.
Thank you SO much.
