The Voodoolab Pedal Power 2 Plus has put my days of having flat batteries in my guitar pedals behind me.
Never again will I need to leave a favoured pedal out of my line so that another can have the newest battery!
Come to think of it it makes financial and environmental sense to banish the battery altogether.
Even if you want to simulate the effect that an expiring battery can offer to an effect circuit such as distortion PP2+ has a couple of outputs with SAG (variable voltage) pots to achieve exactly that.
It's built like a tank with eight independantly isolated outputs and has an air of quality about it, and I like the useful options the included cables make possible.
To round my review off I would like to suggest a visit to the forum - yes it does sound a bit sad to have a forum devoted to powering pedals, but nontheless very useful information with a wide knowledgebase on many esoteric pedals and methods by which PP2+ can power.

Would I buy a PP2+ it again if it were stolen or lost? Absolutely yes!
