I've noticed that if I stand directly in front of my amp, about 3-5 feet away, I get an awesome tone. However, If I move to the side or back I get a muddy sound and if I move further away I get an extremely sharp sound. Does anyone know how to fix this problem? Thank you for your help.
Why would you want to listen to it from behind the amp?
I don't. I think you saw that I said I move back. I meant closer to the amp.
Ok. Is your combo sitting on the floor? Get it off there, it will sound better. Are you in a small room? Try a bigger one if you can. In a big room, try a smaller one if you can.
sometimes the room you are playing in can have an effect on your sound
It's a half-stack. I heard something about putting tape over the speakers. Does anyone know about this?
