Sure it’s not the speaker? that doesn’t sound much different that what I was dealing with.

I just finished a warranty repair on the Weber speaker I put in my two stroke, because it was sounding strange and buzzy at high volumes, in particular on an open A string. took me a while to notice it because I hadnt cranked it much initially, and the buzzing was not uniform on all strings.

I had other speakers around to confirm that I had a dud…and after the repair all is well.
