The Tunemaster Chromatic Tuner from T-REX is a tuner pedal which allows you to tune your instrument silently, with the option of using it as a buffer/line driver. It also features specially designed circuitry that cuts tuning noise down to an absolute minimum. When you want to tune, hit the footswitch on the Tunemaser and the signal is muted. The small on/off 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 flat or sharp. The dot in the upper left corner of the display indicates that the note is raised one semitone. 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/off LED will go off.
The Tunemaster can be used in true bypass or in buffered bypass mode. The toggle switch between the in/out jacks should be set to the right for true bypass and to the left for buffered 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 buffered bypass lets you use the Tunemaster as a line driver with an adjustable output level, called the "Beef" control. In this configuration, the Beef control goes from unity gain at minimum to 10 dB of signal boost at maximum. Not only does this buffer 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.
