[sdiy] Stompbox power (was Re: Socket schematic symbol question)

I was going to suggest an "auto-off" circuit that would power the
stompbox down (let's say) five minutes after your last 'power chord'

(wouldn't that just p!ss you off :^)

Nah, you're just overcomplicating things for no additional benefit.
Also, what to do about quiet moments (i.e. what is the signal
detection threshold?) - do you want the popping sounds as the supply
switches on/off?  Probably not.

keep it simple.
