Sunn Bass Cabinet hum/squish?
The 415 Sunn Cabinet I typically use has started to make a large buzzing noise and reacts poorly to lower frequencies, making a squishy, farting, almost chorusy warble
I ruled out the amp head and the cables; the cabinet is causing the buzz. Any ideas on what's wrong? I'd imagine a ripped speaker is causing the chorusy farting sound but what would contribute to a constant buzz? (I turned the amp head down to zero volume and still had a consistent buzz)
