This thing is the 'MacGyver-knife' of my rack:
It provides the power for all my units: amps, effects, loop stations etc and installing this in my system enabled me to get rid of all the extension chords i used to need. Now I only have to plug one cable in.
It transmits a clean power signal which did a lot for my sound.
It protects against any irregularities in the power signal that would otherwise damage any units.
The front panel has a great voltage indicator that makes it easy to see if the incoming voltage is too high, low or if everything is fine.
A solid, reliable power conditioner which I'd highly recommend if you're looking for safe, clean power for your system!
