Hi guys, Last saturday I had a big deal with my Laney Cub10. I was at a small gig, playing my Cub10 through a 2x12 Palmer cab. After one hour of playing we had a short break. During the break I turned unplugged the input jack and turned it off. After about 20 mins I turned it on again and... No sound at all! The power light is ok, the tubes are glowing, but no sound. I checked pedals and cables, but they are ok. Any suggestion?
