Hi, i bought this amp a year ago and it was working fine until i started hearing a buzz when i play any note lower than my g string (standard tuning) i tried different guitars and many different cables without connecting the pedal board. I did the "tapping test" for the tubes and nothing was significant. I took the speaker out and pushed the cone inwards and i heard a very very faint rubbing sound. I started playing and touching part in my amp to see if something is rattling, the only thing that seemed to remove the buss was touching a certain part on the speaker cone. When i touch it from the back the buzz disappears when i touch it from the front the buzz increases.

Does this mean i have a blown speaker or it could be something else?

Thanks
