I'm sorry but I'm not sure I understand you.  Are you saying you need a replacement footswitch?

It would seem you can't get a replacement from LIne 6 or Bogner, as I found this document written by LIne 6: http://line6.com/support/docs/DOC-2476

if you would like to talk to someone, then call Line 6 on their number in California (during normal working hours for California) and talk to one of Line 6's tech support reps, who I'm sure will be able to advice you of what you need to do. http://line6.com/company/contact/

I hope this answers your question

I think the biggest problem is going to be purchase/shipping to Argentina.

If you have family or friends in the U.S., the chances of an easier solution are increased, since not all U.S. based Authorized Service Centers will sell parts to people who live outside of the U.S.

Perhaps then you can purchase the part (it should be available) through Avalanche Pro Audio via their online order form here: http://avalancheproaudio.com/2801.html

If you purchase the part, be sure to provide a family member or friend's U.S. residential address; the main issue here being that I don't know if Avalanche will ship internationally. Once the part is in the possession of a relative or friend, they can then ship it to Argentina.

Hope this helps.
