Hello! I have a problem with my pod hd300. After not being plugged in for a while after turning on the power and loading the software, there is no sound from the guitar for about 20 seconds. The tuner works, the mp3 works but the guitar does not. After about 15-20 seconds it comes sound, which at the beginning is distorted, choppy and then everything starts to be ok. I did a reset. but the problem is the same. Is there a solution for this. Can anyone help me?
