Rocktron VersaTune - Manual (Page 14)

Using the VersaTune
STANDARD TUNING MODE
In Standard Tuning Mode (this is the default tuning mode when you turn on the VersaTune) the LEDs on the front
panel will indicate the following:
GREEN LED - Center LED with the (0 - zero) above the LED will indicate that the note being played is “IN TUNE”
RED LEDs - To the left of the GREEN center LED will indicate that note being played is “FLAT”. The numbers
shown on the front panel -10, -20, -30, - 40 indicate by how many “CENTS” the note being played is off from being
IN TUNE.
RED LEDs - To the right of the GREEN center LED will indicate that the note being played is “SHARP” from being
IN TUNE. The numbers on the front panel +10, +20, +30, +40 indicate by how many “CENTS” the note being played
is off from being IN TUNE.
CENTS - The Cent is a logarithmic unit of measure used to musical intervals. Twelve-tone equal
temperament divides an octave into 12 semi tones of 100 cents each. Cents are used to measure
extremely small finite intervals or to compare the sizes of comparable intervals in different tuning
systems. Usually the interval of once cent is to small to be heard between successive notes.
Step 1 - plug the guitar/bass into Jack 1 or 2 of the Tuner and using the input select button select the appropriate jack
(CH1 or CH2).
Step 2 - play a note on your guitar. Pluck your E string, if needed, adjust your tuning machine on your instrument
until the letter “E” appears in the NOTE Display window.
Step 3 - if your note is flat - the “FLAT” LEDs to the left of the IN TUNE GREEN LED will light. The farther away
the RED LED is from the GREEN IN TUNE LED the more flat the tuning is. If a Flat LED is lit, tune your string up.
During this process the LEDs will begin to light and move closer to the GREEN IN TUNE LED.
Step 4 - if your note is sharp - the “SHARP” LEDs to the right of the IN TUNE GREEN LEDs will light. The farther
away the RED LED is from the GREEN IN TUNE LED the more sharp the tuning is. If a sharp LED is lit, tune your
string down. During this process the LEDs will begin to light and move closer to the GREEN IN TUNE LED.
Step 5 - Continue with step 3 or step 4 until the flat or sharp LEDs are not lit and the GREEN “IN TUNE” LED lights.
At this point the string is IN TUNE.
Step 6 - Continue steps 2-5 but using your other strings on your guitar or bass.
