Power Adapters
There's not one "Switching Type" (definition: automatically adjusts between 100-240 volt wall voltage) power supply that doesn't Hiss, Hum, or make a noise like a siren through guitar effects pedals except for a Fulltone IPS! It's getting harder and harder to force these Power Supply companies to build something up to my standards, so I've gone back to the Dead-quiet Class 2 (USA, Japan, and Canada only) power supplies.
We still have a few hundred IPS-9 adapters, get 'em while you can, and our FPS-9+ and FPS-18 are Class2 and ready to ship for anyone in USA, Japan, and Canada.
