plastic knob missing
 

Hello, some people know I have on Virus Classic Desktop, I bought it on Ebay few weeks a go with one plastic knob is missing, I bought one in a electronic store but is different, I contacted already a few different places for try to buy one replacement used or new or even from a different Virus (I think are all the same size and form) but nobody reply back to me, the question is if some one have one for sale or where I can order it, please send a private.
Thank you.

Hey Wax,

Firstly contact the official Virus dealers (retailers) for your country, and they will be able to put one on back order for you.

Failing that, contact these guys: http://www.synthesizerservice.de/index.php?lang=en

They are the hardware branch for Access Music, and are based in Germany. I managed to obtain some spare potentiometers for my Virus from them a few years ago, so hopefully they may have some spare knobs that you can purchase too.
