My HD500x has been a true workhorse since I purchased it in January 2014. I love it to death, and get complements on my tone all the time (even from tube purists). Lately however, I have been experiencing some technical issues with my unit and was hoping someone may be able to offer some advice. This is my primary rig. I don't use any other amps or effects and run straight to the board. The issues have been as follows... Several months back I started experiencing issues with my unit automatically switching patches on the same bank. Or, it will automatically switch to the tuner. While this has been intermittent, this is my main rig and I can't have it switching random patches in a professional environment... I've noticed the unit has become increasingly susceptible to power issues. Whether it's wonky power at a gig or running through different power strips, I've noticed some buzzing and glitching issues. The glitching for example started at a gig this past weekend. Sound from the unit would basically cut out every once in a while for 10ms or so. Really strange. Plugged the unit directly into my bass player's power conditioner and the problem subsided for the rest of the gig. Don't know if problem 2 is related to problem 1.... Plugged the unit in tonight to rehearse for gigs this weekend and noticed several of the patches had a "washed out" sound. Like the unit was adding reverb to the patches. Re-sent my patches to the unit and problem persists. Hopefully some of you guys have had similar problems and might know a quick fix. Want to eventually upgrade to the Helix but, as I am a full-time musician, it's a little out of my price range for now. Any help would be greatly appreciated! P.S. Forgot to mention this earlier. I have replaced the original power supply with an official Line 6 DC-3g purchased from Sweetwater. The original had kinks and a light cut (primarily due to me coiling the cord around the brick).
