Hey guys!
I'm using a Big Ben Overdrive. It is a tube pedal, and there's a nice, blue tube glowing whenever it is plugged in. Now, since the tube stays on even when it's bypassed - should I plug it out of the electricity whenever I'm done playing? Can it harm/wear out the tube if I don't?
No, it won't. I mean, tubes have a certain lifetime, sure, but switching them on and off all the time puts more strain on them than just keeping it on.
