I don't get complete cutouts but do get occasional volume drops for second or 2 with my Samson Airline. This can happen several times during a gig. The signal is still there just goes quiet.
Definately not a line of sight issue and tried all the obvious things, new batts, different leads, proximity to other gear etc to no avail. What's more, I cannot get it to fault at home/rehersals which is bugging the hell out of me. SO much so I'm temporarily back to using leads.
Wondering if it has the same cause as the complete cut outs?
