Since so many people seem to be posting that theirs died, it's hard to tell what the actual lifespan is for these amps. I wanted to note that my relatively early unit (pre-Drop branding and in use since Aug 2019) is still working. It's been my primary amp and has been powered on almost constantly since I got it. I regularly use the front 4-pin XLR and the 1/4", both usually plugged in at the same time. In the back, I use the RCA in and RCA passthrough.
bamcgregor89nah mate lol, i've had my 789 for years as a daily driver she's still kicking. in fact she's just starting to have some POT issues and I came around looking to snag another one.
