Re: Noobish Question about Heads not being plugged into cabs...
Agreed, there can be a small amount of current going through the transformer when it is on and out of standby, probably not enough to do any damage for a short period of time, if you left it on for days, it might do some damage. This signal is most likely just circuit noise being amplified, so if your amp is set super clean, there probably won't be much if any, if the pre is cranked, you'll have more noise. But, I agree, I wouldn't recommend doing it. In fact, it is a better mindset to always have a load plugged in if the amp is plugged in. I do flip my amp on standby and switch cabs, that won't hurt it a bit, as long as you plug a cab back in.
