I've got an M-520 mixer that I've had for several years and I think it's time I move on to something else. I purchased this board from Randy Blevins in Nashville around 2009. I just wanted to check here and see if there was any interest in it. I would rather sell it to someone who could appreciate it than put it on eBay. PM me if you are interested. I'm in Jackson, MS.
