Just wondering whether anyone has had this problem. The amp is the first series Vypyr 100. I have Vers 1.66 firmware installed.
If I turn the amp on with a drum machine or similar plugged into aux in (no guitar or headphones are plugged in) I get sound from the speakers OK.
I then plug guitar in - speakers immediately mute and go to headphones. I plug headphones in - working ok through phones.
If i switch amp on with guitar plugged in, it immediately defaults to headphones. Plugging phones in and out again makes no difference. Plugging something into aux socket makes no difference.
Has anyone else had this problem? I have read that the headphone socket can play up but in this case it is funny that speakers work when switched on with nothing in the guitar jack. I did try reinstalling the firmware with and without a guitar lead plugged in but it doesnt seem to make any difference.
