Same here. My Evolver was missing two buttons, the jacks audio out was defectuous and it has a dead led.
I ask DSI customer service hop could i get the components and how many it will cost.
They send me all components for free. I was as surprise as happy.
Very nice to be customer. I must precise that i didn’t bought my Evolver from DSI directly. It was a second hand bought on Audiofanzine Web site.
