I'm not really sure what happened on the screen there, but everything's fully functional great distortion from the tubes as well. Other cosmetic defects are noted in the picture. I guarantee it to work perfectly damages only cosmetic. I'm just gonna put as described because I am guaranteeing its function, but I could've missed something cosmetically. I have two of these and I actually like the way this sounds better, but my other one has a skin on it and I don't want to get rid of it because it's custom and sentimental. Aftermarket PSU included. Factory Reset.
