Agree with Toad!
Really very convenient ... in addition, one can use small pieces of Velcro (included!) to secure the cables that are between the pedals .. it avoids fairly common stuff like jack that moves and just stick in the moving part of wha wha, which prevents the use ..
And centralized power supply which is handy too ...

Oh and I say this because it was one of my fears: I have not had a problem with hum or breath. : OK:
