Howdy fellow gear heads!! I have a Crate
BlueVoodoo6x212 Combo amp 60 watts 2 6L6 power
tubes.
It sounds fabulous except it has a strange vibration
sound when turned up. I tried to isolate the sound by
listening to the rear of the open cab. I am wondering if it
is the Reverb springs? The tubes are very secure in there
sockets. Has anyone experienced this? Any thoughts.
Thanks in advance.
