D’Addario PW-CT-20 Chromatic Pedal Tuner – Used

Quick Product Summary

The D’Addario PW-CT-20 Chromatic Pedal Tuner combines fast, accurate tuning with a large full-colour display and rugged pedalboard-ready construction.

This used example is in Good condition, with cosmetic signs of previous ownership and normal pedalboard use. Its 32-bit processor provides rapid note detection, while ±0.5-cent accuracy and a wide calibration range make it a practical choice for guitar, bass and other amplified instruments.

What Makes the D’Addario PW-CT-20 Stand Out?

Fast, Accurate Tuning

A 32-bit processor provides quick note recognition, while accuracy of ±0.5 cent makes the PW-CT-20 precise enough for live, rehearsal and recording applications.

Clear Full-Colour Display

The vertical colour display clearly shows whether a note is sharp, flat or in tune, making it easy to read from a standing position and under changing stage lighting.

Wide Calibration Range

Reference pitch can be adjusted from 415Hz to 475Hz, providing useful flexibility when working with alternative reference pitches or other musicians and instruments.

True-Bypass Signal Path

True-bypass wiring removes the tuner circuit from the signal path when disengaged, making it straightforward to integrate into a wide variety of pedalboards.

Who Is It For?

The D’Addario PW-CT-20 is ideal for guitarists and bassists looking for a simple, accurate and highly visible pedal tuner.

Its rugged enclosure and clear display make it particularly well suited to live musicians, while its wide calibration range and precise response are equally useful for rehearsal and studio work.
