The Fralin Standard Volume Kit includes a .0025uF ceramic disc capacitor and a 220K resistor. The Volume Kit keeps the tone and volume more consistant as the volume pot is turned down. See Lindy Fralin's website for wiring pictorials. Please note this listing is for the Volume Kit only. Blender Pot not included. Please note the Fralin Volume Kit can vary in appearance, e.g. color of cap and/or resistor.
