Cherub WST-645 features 5 tuning modes: Chromatic, Guitar (Standard), Guitar (Compensated), Bass, and Ukulele.
Inspired by James Taylor's compensated tuning method, Cherub developed and included the compensated tuning mode in the WST-645, which makes the guitar sound more harmonized and in tune while playing.
Here is the compensated tuning method:
