D'Addario Eclipse Clip-On Headstock Tuner, Black
The Eclipse PW-CT-17BK is a chromatic clip-on tuner that mounts on the headstock of a guitar or bass. Its vertical full-colour screen sits on a multi-swivel joint, so it turns toward the player whether the unit sits on the face or the back of the headstock, on a right- or left-handed instrument.
What sets it apart
- Vertical full-colour screen, readable at a glance between songs
- Multi-swivel joint that finds the viewing angle without contortions
- Mounts on the front or back of the headstock, right- or left-handed
- Calibration adjustable from 430 to 450 Hz with two arrow buttons
- Auto power-off after 10 minutes, CR2032 battery included
A tuner for the everyday gig bag
A player who rehearses every week wants a tuner that lives on the headstock, gets forgotten, and answers the moment a string is plucked. That is the Eclipse brief: small, discreet once tucked behind the headstock, and readable on a club stage or in a basement jam room.
The black version disappears against a dark headstock. D'Addario offers the same model in other colours, but the hardware and settings do not change.
Settings
One button turns the unit on and off. Two arrows shift the reference between 430 and 450 Hz, handy for matching a piano or another fixed instrument that is not sitting at A440. Left on by mistake, the Eclipse shuts itself off after 10 minutes to spare the battery.

Frequently asked questions
- Where should a clip-on tuner go on a guitar?
- On the headstock, where string vibration travels well. The Eclipse accepts either face of the headstock: behind to stay out of sight, in front to read it head-on.
- Can it be used on a bass?
- Yes. D'Addario lists the electric bass among the Eclipse's uses, alongside the guitar.
- What does 440 mean on a tuner?
- It is the reference frequency for A: 440 Hz is the standard. The Eclipse arrows move it between 430 and 450 Hz when a band tunes to a fixed instrument set differently.
- Which battery does it take?
- A CR2032 coin cell. The first one comes in the box.
