That is right, I bought the smart-strip to make my PC act like a relay to turn off all the extra stuff in the cabinet. The surprise was that going into stand-by mode would do the same thing. Perhaps this was common knowledge, but I hadn't seen it discussed.
So, I tapped a momentary switch into my PC power button wires so I can turn the cab on with one button. In my XP power settings, I set it to go on standby whenever you push the power button, so with one touch I can instantly go in and out of standby which in turn shuts down my speakers, marquee light and monitor. It looks like the entire cab wakes up and is ready to play in about 3 seconds.
Again, probably obvious to some, but for a rookie like me, it is a feature I didn't expect to have in my cab. I'll keep it on standby all the time.
