The stock factory knobs are sharp to the touch and hard to see in dark conditions or in a bag. These knobs are designed to feel very nice on the fingers with smooth, sculpted edges. And easy to see because they glow after exposure to light. Choose the color and size of each knob and let us know your choices in the "message to seller" when you check out. Refer to the last image in this listing to see all of the color choices available. To see example knobs of the color choices available you can follow this link to see a different listing. Large fader knobs sit 1.5mm higher than the factory knob for easier access. Small fader knobs sit approximately 4mm higher than the stock knob and do not retract flush like the stock one does. All knobs feature a main color along with a phosphorescent white section that glows green when exposed to light (we recommend using a small keychain UV LED to charge the glow for the best effect). After exposure, the knobs will glow for a while. Will fit many models (please contact us if you have a model not listed in the title). Installation is easy: remove your stock knob by loosening the set screw with included Allen keys and pull factory knob off. New knob is a perfect firm friction fit and simply presses securely into place. • Price is for each knob• Designed and produced by Bioluminous - these are not made by Sound Devices• Smooth, no sharp edges like on factory knobs• Many colors available• Embedded stainless steel screw for easy one-finger adjustment• Knobs glow in the dark after being exposed to light and will stay luminous for a little while• These knobs have a friction fit, simply press firmly into place • Knobs can be removed with a plastic wedge tool such as a guitar pick or spudger• Made to order and typically within 1 business day We make a lot of custom parts for sound engineers and film industry professionals.
