and realize amps, in general, should be plugged directly into the mains outlet. When I do this, I can actually feel low levels of current on the metal face plate. Pretty scary.

On the metal face plate? As in wall metal outlet face plate? A metal face plate should never be used on a 2 wire branch that uses a steel outlet box... Replace all metal wall plates with plastic or non breakable nylon plates.

I have plugged my amp into my Panamax surge protector/power conditioner. The grounding issue was resolved.

Model?

So this would work for protection on a two wire outlet? Thoughts...Thanks

Sorry, the metal faceplate of the amplifier.

No, it would not.

It also would not protect from transient surges either. The SPD requires an equipment ground connection.

The grounding issue was resolved.

Resolved by using the Panamax surge protector/power conditioner?

Model? 

Does it use an internal isolation power transformer?
