Hello.I have a big problem with my amp.When I increase the volume level,from my cabinet sometimes come out very loud and terrible sound.It is just like the amp will blow my cabinet 2x12 120W.Ultra gain section - Volume at 5 and more,Gain at 5).Is this bad tube,or something problem with amp?Sorry for my english!
Hello,
Without seeing the amplifier it is hard to determine, we would recommend taking it back to the dealer so they can check it over for you.
Kind Regards
