Hello, I have a problem with my Variax 700 electric guitar. I have the Variax Workbench usb system and it works fine, but when I change tunings or virtual capos guitar tune sounds like and I pass on all models. I've tried everything but I get it. I have also reloaded the memory of the guitar and even alternate tunings in the bank brings custom sound bad. Can you tell me what proffers do? Thank you. I have also a Variax 300 nylon and I would like to know if I can use the cash injection current of the Variax 700 for this guitar.  Muhcas thanks.  My language is Spanish, sorry.
