Hey guys. I have been using the Ultra for years now. All patch changes are done via midi. I just toured February-May 1st with no issues. The very last show of the tour which was So What?! In Texas, my guitar seemed to have gone out. Upon further inspection I notice that no matter what patch I’m on, the output is just DI. It’s like the signal isn’t being processed anymore. I was mid song when they s happened. Any ideas what’s going on? Also the letters on my screen have seemed to dim quite a bit over the year.
