Hi,
I did some setups with my bass heads last night for a recording session next month. Everything worked fine accept my SORADO (68' or 69' Model, SS rec., 6550 tubes, all other tubes with no marks) did an awful snary sound when I played the C on my bass. Didn`t matter what string, it was always the C. So I thought the vibration of the cab could do that to the tubes, but it was the same effect even when the amp was on the floor. All the other notes are fine.
Does that sound familiar to anyone?
Thanks & Greetings
Oliver
