10 x MXR Style Fluted Knob - Large - Black
Just in - these knobs are awesome. Big chunky things which kind of make me think I am adjusting something important in a 60's sci-fi film. They measure an ample 27.9mm in diameter, and fit 6mm pot shafts. Secure fitting with an equally chunky grub screw, they a great for that retro pedal look.
