So nice we named it twice! If you know and love our Armbruster knob... this is still it! We've renamed it The Mid-Fi so that's it's easier than ever to mix-and-match differently sized knobs in the same style.

Our new-and-improved Mid-Fi knob features better set screw tolerances (and a switch to a hex screw), a smoother finish to the top, and machine-line, painted indicator.

Smooth and cool to the touch . . . there's just something that feels good about a solid aluminum knob between forefinger and thumb.

The Mid-Fi aluminum knob keeps the styling simple with a painted indicator and vertical textured grip. It's a super-versatile, professional look. 

Available in cool silver, alongside classic black and sweet mocha. A hex screw secures the knob onto a 1/4" (6.4mm) shaft pot.
