From the seller
Pics are of the actual unit, which is extremely clean - just minor rack wear. I only used it in my smoke-free home studio. AC adapter included.
I will reduce the price of this item until it sells, so if you're at all interested please add it to your watch list so you'll be notified when I drop the price. And of course feel free to make an offer at any time.
