This classic audio control knob calls to mind a childhood spent in front of a massive, wood trimmed component stereo system twiddling knobs in the sunken, shag-carpeted living room of a cool uncle with a mind-blowing record collection who would bark two-word reviews of all the albums you'd pick out: "True genius," he'd say, "Psychedelic masterpiece!".

What we like about it: This solid chunk of aluminum has real heft to it. The styling is simple yet maintains high-quality details--like a machine-line indicator that extends fully to the vertical edge of the knob. A silver hex screw attaches this knob securely and discreetly to any 1/4" smooth shaft potentiometer.

If you're looking to mix and match diameter sizes, complement the Hi-Fi solid aluminum knob with The Big-Fi (25mm OD), The Mid-Fi (15mm OD), The Lo-Fi (12.5mm OD), and The Mini Hi-Fi (10mm). Check out the final picture in our image gallery to see how they look together.
