Constructed with a virtually indestructible die-cast metal housing, the PT-13 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 PT-13 is extremely easy and intuitive to operate, and sets new standards in chromatic pedal tuning design and function. For example, while accuracy to +/- 3 cents is acceptable for other pedal tuners, the PT-13 Chromatic Pedal Tuner is accurate to within +/- 1 cent. Where other pedal tuners have a somewhat unexciting and workmanlike appearance, Markley‘s white pearlescent metallic-colored PT-13 Chromatic Pedal Tuner looks sleek and sophisticated, suggesting the qualities of a high-end, high-performance luxury automobile.
Dean Markley‘s PT-13 Chromatic Pedal Tuner can handle every tuning situation, operating in a frequency range from 27.5 hz - 4,186 hz. The unit is easily transportable and lightweight, weighing in a just under a pound (0.93 lbs).
