Tuner
or your convenience, ToneLab houses a built-in auto chromatic tuner that
can be calibrated between 438 Hz and 445 Hz.
TUNING PROCEDURE
1. Simply press the TUNER button (3.7) and the auto chromatic tuner will be acti-
vated.
2. When you play a note on your guitar, the nearest pitch and a tuning meter will
appear in the name display (3.8).
The note names are displayed as follows.
3. Watch the meter, and tune your guitar.
4. When you’re finished tuning, press the TUNER button once again to return to
the mode you were in.
STEP ON IT! If the optional foot controller is connected, you can use it to activate
the tuner. In this case you’ll be able to tune with the output muted (Silent Tuning
Mode). If you’re using silent tuning mode, defeating the tuner function will simulta-
neously defeat muting, and your sound will once again be heard. ToneLab’s tuner
function will be defeated when you press any button other than the TAP button, or
operate the PEDAL selector.
CALIBRATING THE TUNER
The built-in tuner is automatically calibrated to A = 440 Hz (a.k.a. “concert pitch”)
every time you switch ToneLab on. If desired, you can recalibrate the tuner in the
range of A = 438Hz to A = 445Hz. Here ís how you do it:
• While the Tuner is active, the value display (3.10) shows the frequency of the
reference pitch. Use value knob 3 (2.5) to set the desired frequency.
IMPORTANT NOTE: When you turn on the amp’s power, the tuner automatically
calibrates itself to A = 440Hz. So, if you’ve recalibrated the tuner please remember
that your recalibration will be “lost” as soon as you switch the amp off.
