Antares ATG-1 power supply in Europe

[piriolirio]

Hello VGuitar players! I've ordered an ATG-1 in Japan, of course it will come with a 110V to 9V adapter.
I need to buy a correct AC-DC adapter for Europe (220V). Which one is the best? I downloaded the manual
but there is no info about amperage and polarity. Is there anybody experienced with this?
Thank you!

It uses a standard center-negative 9V power supply and draws 700 mA.
