Hi, I've had the GoXLR since Christmas and it's been working great until yesterday. Yesterday I noticed that my 3rd slider was at the top of the goxlr but the mix was set to 0%. It appeared that the slider completely broke but if I press down on the slider while I use it it works again. If I press down I'm able to move the volume back up for a few seconds before the slider goes black and the volume goes out again. Is there any fix for this? or should I send it back and see if they can repair it? Any advice is appreciated.
