The Voodoo Lab Pedal Power 2 is a universal power supply for all battery-operated guitar pedal effects. New features include two outputs that will power Line 6 modeling pedals and two outputs that can have a variable voltage "sag" to emulate dying carbon batteries. Like the original Pedal Power, each of its eight outputs are completely isolated, short circuit protected, regulated and highly filtered. The Pedal Power 2 comes complete with cables, detachable AC power cord, is hand made in the U.S.A. and carries a 5-year warranty.
I've wrestled with various store-bought and custom-made power supplies over the years, but this was the first time I was able to connect everything in minutes and get great results without hum or profanity -Guitar Player
Each output is completely isolated. This means that you won't have any ground loops or interaction between pedals that can cause hum and noise. It also means that unlike other "common ground" power supplies, you can run effects that have both negative and positive grounds without difficulty.
There are two types of Boss pedal effects, which specify either PSA or ACA type power supplies. Boss pedals specifying the PSA type adapter operate at 9V like most other pedals. Boss pedals which specify the ACA type adapter operate at a higher voltage.
The Voodoo Lab Pedal Power is the only universal power supply available which will power any type of Boss pedal effect. There is a selector switch for each DC output on the bottom of the Pedal Power to select the correct voltage.
Short Circuit Protection
Each output on the Pedal Power is short-circuit protected. This means that if you have a short in a power cable, or one of your pedals malfunctions, the Pedal Power will temporarily turn off the power to that pedal. All other outputs will continue to function normally and the Pedal Power is not damaged.
Power transformers create an electric field that can cause hum and noise in your effects. Some effects, such as wahs, are particularly susceptible to this. A toroidal transformer has a specially designed core that greatly reduces this electric field. The Pedal Power uses this type of power transformer so that your pedal board is quiet.
