I just bought the HB Powerplant because I plugged my pedal independently on strips & it was starting to worry ... Having nosed on lots of forums, I left and tried ... Nickel is!
The pros: price (oh !!!!!), all cables supplied, it looks to me like it's sturdy stuff ...
The -: leaflet in English & German, no specification on the cables (polatités reversers, etc ...)
Value for money most interesting!
You do again this election? At that price, yes! If I sub, I opted for the famous Voodoo, but ...

To conclude, I use effects (5 pedals) upstream and in the preamp, and I read some topics saying that Buzz ... Me, no problemo! I'm thrilled!
