As you probably know apple has released a new software update which enables you to set a volume limitation. What they don't tell you is that your european ipod keeps being capped. Even when you max everything you keep the firmware limit.
As usual the program gopod can uncap your ipod and you can enjoy full sound again.

awesome looking website

any effect at all on US ones? (i dont think there will be, but the site lacks an FAQ page)

Nope they are already unlocked to play at maximum level.
