Over the past 20 years I've had these as the power for all of my pedal setups. I have a pedal board setup for Fender guitars and a setup for Gibsons because not all pedals sound good with humbuckers or single coils. The one standard that I have in my setups is the Vodoo Labs Power 2 Plus. I have had other power supply pedals over the years and there has been hum. Not so with the Voodoo Lab. That's probably the MAIN reason I use them. I suggest getting one of these while around. In the quest for "New and Improved" products, manufacturers have a tendency to "Fix" things that aren't broken.
