I haven't used a scope, but I have had some laughs plugging things into the same circuit as high gain guitar equipment.

Yes please, let's amplify those audible frequencies to audible levels. A good PSU goes a long way.

By the way, if you are ever tempted to measure AC with an oscilloscope, please use differential probes to reduce the risk of damage/electrocution. It is very easy to create a pretty significant voltage potential across your probe and reference when poking around with high voltage.
