+1. Thats how i roll. Takes me about 1 minute to set up the rest, than i tune my guitar, then i hit standby and start rocking.Usually when I get somewhere I plug in my amp first and power it on and then continue setting up my gear (5-10 minutes depending on how much BS'ing I'm doing) then I will plug in my guitar and click it out of stand-by.
This. "Time after" is wholly irrelevant. It's just like a light bulb - turn it off. The temperature of the tube in operation is not much, if at all, higher than the temperature while the heater filaments are running but the amp is in "standby" mode.Standby puts power to the tube heaters.
Tubes don't cool down when the tube heaters have power going to them.
Axe Fx is off.Amp is off, and in standby.
Turn the amp on.
Wait 30 sec
Flip off standby.
On stage, keep amp on but in standby.
When done playing, throw amp back into standby, unplug guitar, unplug guitar cord from amp, turn amp off.
