joeymc93 Posted November 11, 2022 Share Posted November 11, 2022 Hi all, Have been dealing with the input impedance issue for some time on my Pod Go Wireless, which I had reasonably assumed was a hardware issue on a bad batch but have recently changed my mind. My unit was sent off for repair by the store I bought it from, returned with no fault found so we set it up for some testing using the affected unit, a demo unit, and an HX Stomp all running the same exact amp and cab model, nothing else. The demo unit and the HX Stomp sounded identical. My affected unit had the obvious high end roll off that it did before. We then updated the firmware on the demo unit and restored it from my backup. On plugging them back in, the demo unit now has the impedance issue on all its patches, exactly the same as mine. What’s weirder is this persisted even after doing a factory reset and rolling the firmware back to 1.3… extremely unusual. I had one or two patches in the backup where the JSON files were edited to gain one extra block, is it possible that this isn’t as safe as many had thought? General consensus seemed to be that the risks of anything leaking to hardware or firmware were very low, however this has me concerned. Or is a corrupted backup file possible having gone through many update processes? Any thoughts appreciated, I’m communicating this with Line 6/Yamaha in Australia to try and get this identified and sorted out. Missing the unit!

voxman55 Posted November 12, 2022 Share Posted November 12, 2022 As per our facebook chat, its hardware. Fixed by removing a capacitor on input circuit. Contact Line 6 support and they will arrange the fix free of charge. Quote Link to comment Share on other sites More sharing options...
joeymc93 Posted November 13, 2022 Author Share Posted November 13, 2022 Yes thank you, the reason I'm questioning this is that the backup from my affected unit essentially induced the problem into the demo unit that was working perfectly well.

Can't answer that but there has to be something else going on eg perhaps the global EQ was on/set differently - but it's definitely hardware & not software.
