The same problem is happening with my 45000, the headphone pan knob has no effect, so the headphones always get sound and at a level louder than I usually want. It never did this before a month ago, and I have had my 45000 for about two years now. How can this be fixed? and/or what would be causing this? I have unplugged the unit and let it sit for days to see if it would magically reset or something and that has not worked. Just tonight, I was using it and for a second I was able to turn the headphones all the way down, and then back up, and then suddenly it went back to always being really loud all the time. I think I may have heard a bit of a click around the time it stopped working again. Not sure what that would mean. It was not a click I felt on the knob itself. Just seem to recall some kind of click sound happening, not sure if it was audible just over the phones’ speakers? or if it was audible just ambiently without wearing the phones indicating some circuit having trouble. Hmmm. Hey EHX staff, can you post on this to tell us if something could have blown out somehow? Or what might be causing this? and if its a common problem? Please respond. Thanks guys

Yeah I hear you on all levels. Please make sure to post back afterwards to tell us if it resolved your issue, and what they say the problem is and any details further into explaining that, so that the rest of us like me can figure out what the deal is too, and whether its worth it to fix it. Thanks and good luck!
