This is a vid of a Quasimidi Quasar that I will be selling on Ebay very soon. As you can see from the vid it is in a fully functional order. The only thing wrong with it is that when it is in edit mode all of the functions work but the red leds in the middle of the buttons & the performance number leds do not work for some reason. This does not affect it's functionality & to be honest it was like that when I bought it & has never been a problem for me. I guess it could be an easy fix for someone that knows what they're doing.
