Edirol V-4 4 CH Video Mixer

Powers on and all buttons/lights/dials/levers/toggles/etc seem to be in good working condition. I have gone through and ensured that nothing on the board sticks, creaks, or catches to the best of my ability. Because I do not have the correct corresponding equipment, I am not able to verify any functionality of the mixer beyond what I describe/d here, but again, I see no issues or indicators that would imply internal and/or input/output problems. POWER SUPPLY/CORD IS NOT INCLUDED, but it is available on Amazon for roughly $40, which I have considered in pricing this. Power supply is visible in photos only to show proof that the mixer does in fact power on. Near the power supply input, the mixer specifies exactly what power adapter is required, and if you have other Roland devices like I do, you may already own one (PSB-1U adapter). There are some cosmetic marks on the surface of the board that seem to be sharpie/marker of some kind, which likely could be removed with nail polish remover. Some light scratches on the body but no denting. Upon presentation of photo/video evidence from buyer and return of the item to me, I will issue a refund if it is determined that the mixer has any serious defects that prevent it from performing its intended uses. Please reach out if you have any questions or would like additional photos to assist you with verifying the condition!!
