I've had my 3000 psi compressor to 4500. It never changed tone, or

you're talking about 10 times over.

Oooh! Ya wanna fill some tanks for me?



Sure, but I can't mail them, and I can only fill to 9000 psi.

IIRC European SCUBA divers could get tanks for 4500 psi years
ago.(smaller physical size for equivalent air volume)

I've been away from diving for a while, so I don't know what the current
systems are using. Guess I'm gonna have to google.

There was a move toward getting European tanks approved for use in the
US, but I don't know how that came out.

9000 psi? Bet that first-stage regulator is something.
