Hello everyone! I want to tell you my experience guys/girls. I hope this is helpful to someone.
I bought the Pod Go in February 2020 if I'm not mistaken. I have been with this unit for a long time, playing and tuning almost every day.
After all this time, I always felt like something was missing, but what do I know, right? so keep tweaking my presets and playing around. Ever since I bought a Stratocaster... when I bought it, second hand, I played it for about half an hour with an old amp and it sounded amazing! But when I got back home and plugged in Pod Go... WTF. that guitar was lifeless!
So I was out of ideas until I saw this impedance issue on the forums, and after a while I decided to try the famous BOSS buffered pedal. FINALLY today! A BOSS CS3 OFF does the job. No need to turn it on. The stratum is alive again. the difference is huge i can tell. I don't mind having another pedal, it's not ideal, but hey, this sounds amazing now.
In summary, I can confirm that the impedance problem is real, and that a boss pedal turned off enhances the sound much more.
good luck!
