Independent shopping perspective
The Korena take
Built for reverse 6-in-line guitars, these nickel 406 Series Mid-Size Locking Rotomatics use a post-mounted locking cam and smaller buttons. Put the string through the hole, draw it tight by hand, and begin tuning. The cam locks the string before the post begins rotating, so the string can reach pitch in less than one complete turn of the post. An 18:1 ratio supports precise tuning adjustment.
Strong match
Who this is for
- Restringing a reverse 6-in-line guitar with locking string posts.
