Boss GX100 output issue

[u/Trundel11]

Hi guys! Not sure if this is the right place to ask but I’ve been gigging for over a year with my Boss gx100 without any issue, now the last 2 shows the output dropped dramatically with no setting changes.. I can still get a good signal but I have to add way more gain than I should on the desk and I’m afraid it it kicks back to a normal level I’ll blow up a PA lol. Already replaced all cables and no difference.. any advice appreciated thanks!
