What can I run at 18 volts? or should I ask what not to run at 18 volts

18 volts. This is a grey area for me. I'd like to understand it a little better. I understand not to run pedals at 18 volts if you use 16v caps.
If I only use 35v-50v, can I run these pedals at 18 volts?
If it has a charge pump, that's a no, no right?
If its some sort of fuzz pedal were biasing is required 18 volts isn't a good idea? unless the biasing is corrected?

are there certain common IC's that won't run at 18v?

Is there a list of pedalPCB pedals that you can run at 18? Or not run at 18v?
The pedalpcb king of tone is already at 18 volts dur to the charge pump?, but the original doesn't have a charge pump?

I hope this makes sense. It would be awesome if someone could guide me in this area. Or point me into the direction of something I can read up on.

Cheers
 
It depends completely on the entirety of the circuit in question. Just because a pedal has all 35v caps in it doesn't mean the other active components are capable of withstanding an 18v supply. A more specific question is in order IMO.

And why is running a pedal at 18v important? No amp (of which I am aware) can sustain more than a 3v input signal without being damaged. Some amps are capable of less.
