So I just did a factory reset as you said (pressing A switch while powering up) and the the pedal calibration Volume suddenly lowered while playing a song (using a standard factory patch).

I appreciate so much all the help you guys are giving here and making sure I'm trying all of it. Right now I've been playing on test mode for about 20 mins and no signs of the sound going down, but before that I was playing normally and it did lower for a moment. So apparently the problem DOES NOT happen in test mode. Looks like progress? I can't ID where the problem is though :(

It happens at gigs too... and I obviously don't use the HD Edit at gigs or at the studio

I'm gonna try something that I haven't (and that may be the problem): I think it's somehow related to the master volume knob, as I was playing with the pod hd300 edit open, so it can't be the CH Vol., otherwise it would've been edited. It also can't be the volume pedal, as I would also lose gain, which doesn't happen. So the only other volume controller that could interfere on that is the master volume. If it isn't the master volume (that might be dusty or defective), the only other explanation would be some kind of in-built volume clipping, which I have already tried to minimize (I've tried a lot for example using low CH. Vol - around 40% - and master volume at 50%, still happened) So I guess I'll try to open this and clean it up or something like that...

it isn't, sadly :( it's happening right now and I'm not even moving, just letting it sound and the volume goes up (to normal levels) and down... I don't think I can get up on stage unless I fix this...

I am extremely frustrated with this. It's so f*ckin sad when I'm playing at a gig and bam the volume goes down from nowhere. When I'm practicing at home it isn't any different, I'm playing and suddenly the volume lowers by itself. I've already reinstalled the firmware, I've done a factory reset, I've done this: "1-first I have to recommend u to update ur pod hd300 flash memory firmware to version 2 , if it is already re-install it , wont hurt 2-2nd What ur experiencing might be the act of The pod hd300 sound normalizer , which means ur channel is too loud and it reduces the volume to prevent amp overloads , so the solution is decreasing ur channel volume and increasing the overall (output) volume from the back of ur HD300 , this way u can both have a loud and un-normalized sound which is cool right" I've also tried this: ""Try this, rotate all your pots fully a dozen times, do this every now and then to keep them clear of any muck that might be getting in there. You will also notice that there is like a null area on each pot near zero and 100 percent. Once you have your settings assigned to your patches and don't need to make any adjustments while playing, you can "park" the knobs in that null area where they won't deliver a value change due to vibration."" I have tried using different sources (my amp, my friends amp, my headphones), different settings (studio/live, amp/line) I've tried different cables, nothing works. Please, help me!!
