Hey, I'm a noob here and I have a MK V Combo with an issue with the lettering rubbing off. Has anyone else had this happen to them? The amp was purchased new in June Serial #150. Is this something I can get Mesa to replace under warranty? I don't like to spend $2K on an amp and have the silkscreened lettering rub off at the slightest touch. I put a little bit of my wife's nail polish on the "ON" that's why it looks different. This is a bit disappointing to say the least...
