I have a Fender Blues Deluxe, and it clicks every so often when I'm done using it. I'll play for a while, turn it off and unplug it, then for the next 20 minutes to an hour it will click at random times... Is this normal? I don't have much experience with tube amps..
My car does that too, it's just cooling down.
Yeh, i think it's the tubes cooling down
