Hints and Tips:
The X-Tune is sensitive - so it is not necessary to strike your string very hard -
standard string attack will work. Additionally, if you are in a loud environment try
using harmonics to tune your instrument. Lightly touch the string over the 12th fret
of your instrument and pick the string with normal pick attack. This will create a
harmonic. It will work on all strings.
The MUTE Silent Output Jack is ideal for tuning in live situations. This will allow
you to tune without everyone in the audience hearing you tune. Additionally, this
will mute the signal going to your amplifier which will help you keep down noise
generated if you are using a high gain amplifier.
When using the X-Tune with the Continuous Output Jack, make sure you turn off
your tuner once you are done tuning. Leaving the tuner on will run down the
battery.
