They offer two versions of the same effect but normally with some extra features. For example, the Phaser has two speeds, and when you change speeds, it actually takes time to speed up or slow down, rather like a Leslie. Unfortunately my 18v adapter went missing and I didn't get to try them out until recently and two of them don't work at all. A shame, as they are nice pedals but being dual function, the circuit boards are crammed full of components so it's not easy to identify anything, even the circuit path.

If you've got a Digital Multimeter, try plugging in a guitar lead into the input with the bottom cover removed, and then check to see if the circuit board is getting any power, that's the first thing I'd do with those non-functional pedals, if no power is getting to the circuit boards, try checking if you're getting power on the solder lugs of the power socket, if you are, then it'll most likely be a break in the power wires going to the circuit boards, hope that helps.

Let me know how you go with them.
