The solid aluminum Pantherkill knob takes on tone in a single, spinal-cord smashing bite. Why so blood-thirsty?

With a slim 12.5mm outer diameter and sandblasted finish--in both matte black and matte silver aluminum--this audio control knob adds a seriously cool look and feel to your gear. Kind of like a panther crunching the skull of a young deer--it's sleek, unexpected, and undeniably dominant.

The knob uses a hex screw to fit securely on a 1/4" smooth shaft potentiometer, and its unique matte finish provides extra grip that can be especially useful when making adjustments in tight proximity to other knobs--for pedals, pro-audio gear, and modular synths.

Also available in two outer diameters for 18T knurled shaft potentiometers:

Small - 10.2mm

Medium - 12.7mm

We created our sandblasted knobs in conjunction with Jim Smith of Catskill Analog, a man who knows how to obsess about knobs. Go check out his seriously cool tape echo!

(And, P.S.: While we do stand by the absolute killer nature of these knobs, the name's true origin comes from Jim, whose business is based in upstate New York where there are lots of place names with the word "kill" in them, derived from the Dutch language meaning "stream." So, if you're vegan, just think of these as really, really pretty knobs you'd enjoy taking on a hike in the mountains.)
