I am looking to get a pedal board. I have seen a few power supplies that look great, but they tend to be a bit pricey. I was wondering if anyone had any ideas about inexpensive power supplies? There are a lot of Chinese-made power supplies (Caline/Donner/Ammoon) on Amazon, but I got burned when I bought a Muslady pedal a few months back, so I am a bit cautious. Any suggestions?
