SWR LA15 Buzz

[MostlyBass]

I've got an SWR LA-15 that will buzz and growl nastily when playing a low G or open G.... Other notes are fine...Nothing seems loose.... and it seemed to develop the problem out of nowhere.... any ideas??
Thanks!

It's the speaker. Try backing off the low eq. A single 15 will only go so far, and just because it's part of a combo amp, does NOT mean it can handle anything the amp will provide.
