Yes after each time I have done a fresh software install, and I do the upgrade whenever there is one.
As for the venues the 1st two times it was in a pub/restaurant/venue that I have heard other bands have problems with power which is why I bought the surge/spike protectors.
The 2nd venue was a small music venue, I cannot vouch for the electrics there either.
I have a tester that I use at all venues to make sure there are no problems with wiring.
Both these venues I have gigged many times so it seems pot luck!
Saturdays gig was at a larger music/ theatre venue, the cafe/kitchen was closed for the gig and they did mention that the gig room was on a separate ring main.
I have attached the video, sorry its dark the band were still playing at this point.
Sorry it won’t load i’ll have to make the file smaller!
