Yeah, you don't want an *actual* power conditioner. I have a couple, for other purposes; their key components are 2000 watt isolation transformers, which weigh about 25 kg each, and wouldn't be a cost-effective solution to amp/stompbox noise. A little, lightweight one, like is often built into a surge protector, uses a couple of capacitors to shunt off noise from the power lines to ground, and should be sufficient in most cases.
You can also get various forms of inductors, such as beads and other doodads made of ferrite, which can help with RF noise on power lines.
Either capacitors or inductors can also be incorporated into the signal path, to do the same for noisy signal connections (like equipment that amplifies RF).
