You need to get in touch with Yonex USA:How did you get them? I've been looking online and it seems there are no US distributors.
Yeah, IIRC on yonex machines it’s called lockout mode.I just realize PT 8 deluxe has this function that is uncalled for, but interesting to stringers that have a sudden spike customers that are used to "crank-ed stringbed stiffness"
It is the "normal" stringing method that makes the machine to apply tension to the strings like how a cranked does. LOL.
on top of that. It stacks with prestreching . It means you can do "crank" with X % prestrech.
Ok it's crazy.
