Hold down the next and previous preset buttons

Ahhh... I'll have to try that. That sounds like that just might work...

I dont mean to sound sarcastic, just currious: how would you change the volume then?

The knob would still have to adjust the volume by default, yes. But what if pressing the knob once brought up the tuner frequency adjustment, instead of loudness, or whatever comes up right now? That would probably work out pretty cool.
