Marked "RUWIDO" on side, "10K + 1g" on bottom. New, unused. Five available. *At this point the best I have offered to many people is a very similar fader, usually Japanaese with correct length fit hole to hole mount, but 10k or 20k fader value will work virtually the same. Many faders are pulled from wrecked consoles but faders can be cleaned, tightened or sometimes are like new. I will not sell worn faders. Average cost is $8-$14 for basic faders, $14-$22 for these special glass carbon epoxy types. Please show a picture that clearly shows hole to hole length.
