I'd say Yes, this is on their FAQ's:
[url="http://www.markbass.it/support.php#panel6"]Can I use my Markbass amp in countries with different voltages?[/url]
[color=#333333][font=Oswald, sans-serif][size=4]No! Your amp/combo was manufactured to be sold and used in the country of purchase, and is factory preset to that country's voltage. If you use it in a country with a different voltage without using a power converter, it will not work and may be seriously damaged.[/size][/font][/color]
[color=#333333][font=Oswald, sans-serif][size=4][size=4][font=arial,helvetica,sans-serif]So the voltage would be the same, maybe ask MarkBass themselves via email? I don't know what their response time is like, mind you.[/font][/size][/size][/font][/color]
