Had to send Bugera back. Tube rattling inside and they don't want to send me a replacement tube but to send the whole thing back. Behringer wasn't any more help. Nearest service place 2 hours away. So....I ordered an Eganter Rebel 30. Always wanted a Rebel 20 but didn't want to spend the money. Glad I waited and they came out with this. I want to tell you the Bugera sounded great but I had problems with the first one I had and this one scared me a little. Please no " I told you".
