Wait a minute, if you are using a vintage amp, are you not supposed to use the vintage plug ( two pin...non grounded) that came with it! Plug that into any wall outlet and you risk....well you know.
Change the plug on the amp end to a decent three pin grounded...

Not so fast. It may not be a simple matter of just changing the 2 wire power cord and plug to a to a 3 wire cord and plug and ground the chassis of the amp. The OP needs to get a schematic wiring diagram for the guitar amp. Some AC line power wiring modifications will, may, be needed.

 @jea48   Just to be clear, I'm NOT suggesting that he change the original plug. As I stated, this mod will change the value for many collectors...for the worse! Yes, believe it or not, an all original two pin plug is sometimes preferred on these vintage pieces! Nonetheless, the fact that the original cord and plug are attached to the amp seems to me to off-set any benefit that a new wall outlet will likely have.

@ daveyf

Agree.

Thanks guys. I should of clarified. I'm not rocking a vintage amp with a 2 plug prong. My main guitar amps are from the 80's ( Mesa Boogie Mark II & III ) which aren't vintage enough to be 2 prong. But thanks for the concern!

@jerzey2222  I use a Mesa Tremoverb 2 12 combo, I will be interested to see if you hear any difference with your wall outlet. I use the excellent Oyaide R1 for my audio system...but the standard plug for the guitar stuff.
