I have a 70s Custom Telecaster that I installed a Graphtech Ghost Piezo system into with onboard preamp. I can plug this guitar into any amp and it sounds fine.
I can plug it into my HX Stomp and it sounds fine. When I plug into my POD go it has enough signal to tune the guitar but only produces a muffled super low sound (unusable).
If I plug my guitar into an eq and out to the POD go it sounds fine. If I plug it into an acoustic preamp and into the Pod go it sounds fine.
I have - reset to factory settings, after the issue a new update popped up and I updated and it still doesn't work.
I love my POD go but can't use it on this one guitar.
