Hello,
I've recently bought a Flextone III XL and I'm pretty disapointed.
I have the same problem detailed in this old post (I don't know why Line 6 locked all topics)
http://line6.com/support/message/476712
In my case, volume changes coicide when the light of the channel turns off (both in the floorboard and in the amp).
Can it be caused by a digital issue?
I know lots of people had the same problem with this amp. Does anybody knows how to fix it? Technical support is very very far away from my home.
I can't belive Line 6 don't tell me anything but "take it to the technical support". For what I've seen this is a typical issue of this amp.
I would apreciate any help you could give me.
