Do you need that extra push over the cliff? The Medium sized GTE (Goes To Eleven) Knob can fit onto potentiometers with a 6mm wide shaft thanks to a brass insert with a set screw.
We know that most of you are playing at ten, but with the GTE Knob you can go… one louder.
Note: It goes to eleven.
Dimensions: 28.9 x 18.3mm
