Accessing Coil Tap / intonation


Recommended Posts



A guitar is perfectly intonated, when the active vibrating length of a string is exactly halved when you play a note at the 12th fret. Its physics that this results in the first harmonic/double frequency.


That’s the theory, but in real live results can differ. For example an unbalanced string compromises accuracy. Please check that the strings look fine. When the strings are new please bend them before intonation.


Now start the intonation process by selecting the underlying preset. Normaly you choose standard EADGBe tuning, but Powertune can intonate on any tuning.


Pull MCK, rotate clockwise to LED-Peg and press Enter to select standard EADGBe tuning. (Note: You can access standard tuning in all bank colors by clicking on LED-Peg). Strum the strings to tune the selected preset.


Next step is to activate Intonation Mode. Select red bank (rotate MCK counterclockwise all the way down and press Enter untill you see a red dot on the MCK). Rotate MCK to LED-Peg and press Enter for 2 seconds to activate Intonation Mode. LED-Peg is shining orange while Intonation is in progress, string LEDs (E, A, D, G, B, e) are shining red.


Now strum gently ONE string, for example E. Powertune detects the frequency and switches the corresponding LED to orange. Now press down the string in the 12th fret and strum again only this string. Powertune detects the frequency which should be excactly the first harmonic/double frequency .


When the frequency has doubled (1 cent tolerance) the coresponding LED will shine blue, what means that this string is intonated.


If its flat, a red number will be displayed on MCK. Please turn the screw at the correspondig saddle COUNTERCLOCKWISE. Turn as many halve turns as displayed, for example a red 7 means: turn 7 halve turns counterclockwise.


If its sharp, a green number will be displayed on MCK. Please turn the screw at the correspondig saddle CLOCKWISE. Turn as many halve turns as displayed, for example a green 4 means: turn 4 halve turns clockwise.


After you have changed the position of the saddle by turning the intonation screw, the process restarts for this string. Strum this string again. You will notice that Powertune retunes the string because of the change of the saddle. When all string LEDs are shining blue you successfully intonated your guitar.



As you know, you can easily change the pitch of a fretted string up to 10 cent by applying different forces. Also the position where you press down the string has an effect on the pitch.

To get the best results, please use a consistent force and position.


During Intonation the tuning precision is set to maximum automatically. You may notice that it takes a little bit longer to detect the pitch.


Don’t expect all saddles to be at the same position after intonation. Its normal that they differ.


Please use a suitable screwdriver to avoid scratches on the tailpiece or bridge.



You play. We tune.
