Hi there! What can it be, when sometimes i turn on my amp the channels simply don't response, there is no led light and no sound. But when i plug a footswitch out, led and sound start to be functional. So it rarely occurs, but still occurs. Should i worry about it? Footswitch itself works properly by the way.
Hi Wayne,
Thank you for your comments, we would recommend the amp is looked at by an engineer to be checked over
