Reverb feedback

[bent]

Hi all,

I have recently noticed that when I set my AD30R's reverb and master volume above 3 o'clock, I get a bad feedback noise. It happens even when gain, guitar, and eq all set to zero. I have no problem when gain and reverb set to full, with master volume below half, its just when master goes above half, even when no gain. I have no effects and it also happens when nothing plugged into the amp. Should this be? Thanks in advance for any help.
