My Marshall TSL 100 is making weird noises and I don't know why!?
Anyone that can help me? I can describe the sound as if you here someone pounding on a wall and you are on the other side. Like a muffled pounding. The noise is always at the same volume, no matter what I do with the volumeknobs on the amp. I've tried using different cables from the guitar to the amp and from the amp to the cab.
All of the tubes are working as they should.
It's a really irritating sound, I've had problems with it before but than I didn't use it for 2 days and then it was fine again.

Anyone who knows what may be wrong?

sounds like the speaker is bust, but take it to a shop rather then mess with
