Congratulations TUNEMASTER in use
on your purchase of the TUNEMASTER, a premium guitar/
bass tuner from T-Rex Eects.
Your TUNEMASTER is a true bypass chromatic tuner, which
allows you to tune your instrument silently, with the option
of using it as a buer/line driver. The big note display, clear
“in-tune” indication and super simple operation makes tuning your instrument a breeze. It also features specially designed circuitry that cuts tuning noise down to an absolute
minimum.
The TUNEMASTER is designed to be very easy to use. When
you want to tune, hit the footswitch and the signal is muted.
The small on/o LED tells you that the tuner is now active.
Play any note and the TUNEMASTER will display the name
of the note, and indicate whether the note is at (left side
arrows) or sharp (right side arrows). The dot in the upperleft corner of the display indicates that the note is raised
one semitone (G#, D#, A#, etc.). Once the note is in tune, the
whole display will light up in green. To go back to playing,
hit the footswitch and the on/o LED will go o.
Bypass mode
The TUNEMASTER can be used in true bypass or in buered
bypass mode. The toggle switch between the in/out jacks
should be set to the right for true bypass and to the left for
buered bypass.
The true bypass routes the input signal directly to the output.
In essence, when you are not tuning, it is as if the TUNEMASTER isn´t even there.
The buered bypass lets you use the TUNEMASTER as a line
driver with an adjustable output level, called the “beef” co n -
trol. In this conguration, the “beef” control goes from unity
gain at minimum to 10 dB´s of signal boost at maximum.
Not only does this buer your signal to avoid treble-loss,
but it also gives you the ability to boost the overall signal
level, compensating for long cables and/or signal losses
from running a lot of pedals. You can also use it as a pick-up
booster, if you need a little more output from your instrument.
Try setting the “beef” control at minimum and listen to the
sound when using either bypass conguration. Depending
on your setup, you may hear a clearer, more open sound
when using the buered bypass. Then adjust the “beef”
knob to taste.
