This is a great condition MP8R that was only occasionally used in our studio drum room. We're just selling some items to recoup funds, but this works wonderfully. I haven't reset anything on it but would be happy to do so if you would like before shipping. The only very small issue I could find is that the tiny, translucent plastic center portion of the button selector for channel 1 has fallen out, but it does not impede functionality at all, it's just something to note. I've seen that on other MP8R units before, I think it's just from repeated pressing, perhaps with the fingernail instead of the pad, something like that.
I also have posted another MP8R, as well as a bundle that has both preamps, a rolling rack, two headphone mixers, and two monitoring headphones. If anything in one ad sells, I'll update the others to reflect it. Please let me know if you have any questions!
