Hello,  
  
Yesterday my new Variax JTV-89 came, unfortunately pushing Guitar Model Selector doesn't start variax, LED won't lit :/ Battery is fully charged. Does anyone know what is the problem? 
  
  
I thought that changing firmware to 2.0 will help, unfortunately, after installing version 2.0 problem is the same. 
  
Sorry form my English ;) 
  
Best regards 
Pawel
