V-AMPIRE LX110

7. TUNER

The built-in tuner can be switched on and off by pressing the UP and DOWN buttons simultaneously. This switches the V-AMPIRE to bypass mode.

7.1 Tuning your guitar

The chromatic tuner automatically recognizes the frequencies of all the standard guitar notes. For the A string, this means a frequency of 110 Hz. When you plug your guitar into the V-AMPIRE and play an open string, the tuner will recognize and display the note. Since the tuner uses an auto-chromatic scale, it can also recognize semitones which are indicated with the flat symbol “b” in the display.

However, it may happen, for example, that a note is displayed as “A” but is actually slightly out of tune. This is shown by at least one of the four LEDs at the bottom of the display lighting up. In certain cases even two of the LEDs may light up indicating that the pitch of the note played lies between the pitches represented by the two LEDs. When the circular tuner LED in the middle lights up, then the note played is in tune.

7.2 Setting reference pitch “A”

To give you maximum freedom when tuning your guitar, you can change the preset reference pitch “A”. For clarity’s sake, let’s look at this in more detail.

The so-called concert pitch “A” has been raised steadily over time. For example, the tuning forks used by Bach, Händel or Mozart resonated at 415, 420 or 421 Hz (oscillations per second). Today’s orchestras tune to “A” at 444 Hz, and the Berlin Philharmonic Orchestra lead the field with their own concert pitch “A” at 447 Hz.

The reference “A” on your V-AMPIRE has been factory- programmed at 440 Hz. If you are going to play with a big orchestra that tune their instruments to a reference pitch of 444 Hz, you will need a function that allows you to change your reference pitch:

Switch on the tuner by pressing the UP and DOWN buttons simultaneously, then press and hold the ADJUST control to enter the calibration mode: The display shows “40”, i.e. 440 Hz.

Press and turn the ADJUST control to increment/decrement the reference tone “A” by 15 Hz each. The display always shows the last two digits of the basic tone, given that the first digit is always “4” (“44” = 444 Hz, etc.).

Release the ADJUST control to quit the calibration mode. Any changes made are stored automatically. The remaining strings of your guitar are now tuned on the basis of the adjusted reference tone.

7.3 Tuner Bypass volume

In tuner mode, the ADJUST control adjusts the volume of the guitar signal while tuning up. Turning the control fully left mutes the signal.
