I just got my Helix a little over 6 months ago, Great kit. Been with Line 6 since Original Vetta, POD X3, POD HD Pro, Variax 700, and JTV so not new to updating these units just the whole IR elements. Just wondering after updating if you reinstall the IR's and user presets does this overwrite the new IR's from the update or just add the older one's into memory along with the new ones. Thanks for your advice.

At band practice the other night running my POD HD Pro and JTV direct to the PA with an old Vetta longboard. All things normal, but all of a sudden I started getting volume bursts which I've had before and never solved with this rig and my POD Pro X3. Then during one song the volume just died. I had to turn off the POD and then everything came back on. Weird. Lastly, I have it setup to switch the JTV setting with the patch. During the last song I have an acoustic guitar selected with the patch. All started okay, but then about half way through the song the guitar tone switch to a normal clean electric. I could hit the patch button and it would return, but then did it again. I finished with the clean tone. Any ideas? I've looked into things like electrcity spikes and I run conditioners. Could the old longboard be causing issues? It works fine with my old Vetta, but both PODs I have owned now have had volume issues. Any help would be great. I'm scared to gig live with this rig until I get it resolved. Regards BobC
