Potentiometer with Built In Knob - 10K ohm

Sorry - we thought that was clever.  And while it wasn't really, this potentiometer definitely is! We've seen these in miniature synthesizers. They're bigger than a trim-pot but smaller than a chunky potentiometer. Best of all no knob required! These have a knurled plastic grip with a white stripe marking. Use it as-is, for a low-cost adjustment Comes as...
