question for G-Major users

have any of you guys experienced a problem with your G-Major where ...it all of a sudden will freeze up and stop producing sound ? this has happened on stage in the middle of songs and it sucks! i try and restart the gmajor but the screen goes away and then when i turn it on it remains frozen on the last displayed patch or nothing at all...and no output or controls work ! :x

it sucks cuz i thought this was the perfect fx companion for my herbert...if anyone has had this problem or can help that would be great!

I've had that before, but only when I was using the external switching jack. I put it down to being a problem with the relays.

I haven't had that so far... sorry
