hello to you all! i have a problem... i use only one preset at my amp and always at the same volume (channel volume at 3 o'clock and master at 9 o'clock). but, today when i turned it on, it was like at volume 0. i turned it off, turned it on but it still wasn't at the volume i played yesterday and the days before. then i cranked the channel volume to max and master at noon and now it's like before. it's something like the power lost it's volume.
any help would be great! :)
