The sleek and sophisticated PT-13 tuner includes input, output, and true bypass 1/4" jacks, as well as 15 LED graduated pitch indicators, pitch and flat key buttons, and a 9V adapter jack.

The PT13 is extremely easy and intuitive to operate, and sets new standards in chromatic pedal tuning design and function. This pedal tuner is accurate to within +/- 1 cent.

The PT13 tuner can handle every tuning situation, operating in a frequency range from 27.5 hz to 4,186 hz. The unit is easily transportable and lightweight, weighing in at just under a pound (0.93 lbs.) although its housing is made from virtually indestructible die-cast metal.
