The Kritz Intonation Compensation (TM)

New, accurate calculation of the Smilefret (TM) positions results in an incredibly pure, open string sound. Our ears hear higher notes less high than they really are. 
Due to this, piano’s (they have a lot of octaves) are tuned with a (logarithmic accumulated) higher upper part. Of course your guitar needs exactly the same adjustment to sound “in tune” with any keyboard. A special bridge fine saddle adjustment adapts the guitar and makes it sound in tune with any keyboard in the highest fretpositions.
The lower Smilefret (TM) positions are calculated in such a way that the player obtains an equal tone balance between open and the depressed strings. It’s so nice to hear it! You won’t believe your ears.
