I have a Marshall Origin 50 Head. Lovely amp. When I run the Master past half way, the amp hisses regardless of anything being plugged into it. Below 50% no hiss. I turn Master to 3/4 and gain down to 1/4 so I can get a crystal clear tone.
Is this normal or is my amp faulty?
Hi George,
Thank you for reaching out, we would suggest the amp is looked at by an engineer, if you contact marshall@elfa.com.au , they will be able to help.
