D Addario PW-CT-23 Pedal Tuner+ User Guide

Quick guide from the manual

The D Addario PW-CT-23 Pedal Tuner+ is a chromatic pedal tuner designed for musicians. It features a high-visibility LED display, a built-in countdown timer for rehearsals or set lists, and selectable buffered or true bypass modes to maintain signal integrity.

Device Overview

The tuner features an input jack, output jack, and a 9V DC adapter input. The main interface includes a foot switch for activation, a calibration button (A415-A475), and a countdown timer button located on the side.

Tuning Operation

The display provides visual feedback for tuning:

• Sharp: Upper LEDs illuminate.
• Flat: Lower LEDs illuminate.
• In Tune: Green LEDs above and below the note illuminate, along with left and right arrows.

Use the calibration button on the side to scroll through reference frequencies between A415 and A475.

Countdown Timer

The tuner includes a timer to help monitor performance or practice time:

1. Press the COUNTDOWN button to select the duration (each press adds 5 minutes; hold to scroll faster).
2. Wait a few seconds until the setting flashes to arm the timer.
3. Press the button again to start the countdown.
4. The green arrows will flash while the timer is active.
5. A five-minute warning is indicated by a row of red LEDs flashing.
6. When time expires, all red LEDs flash and the display reads 00. Press the button to end.
7. Press and hold the button at any time to cancel.

Bypass Modes

The tuner offers two modes for signal routing:

• Buffered Bypass (Default): Converts high-impedance signals to low-impedance to prevent signal degradation over long cables or multiple pedals. The internal trim pot allows for gain adjustment.
• True Bypass: Routes the signal directly from input to output without passing through circuitry when the pedal is off. To enable, remove the back plate and set the internal buffer switch to the off position.

Power and Maintenance

The device can be powered by a 9V battery (included) or an external 9V DC adapter (tip negative). For support, contact [email protected] or visit daddario.com.
