Automatic Guitar Tuner & String Winder

In the middle of tuning, you grab the wrong tool – and everything starts over.

Anyone who wants to tune their guitar before a performance or after changing strings knows the annoying back-and-forth between tuner and crank. The Strummer combines automatic tuning and an electric string winder in a single compact device. Thanks to vibration detection technology, it automatically recognizes each string and turns it at the push of a button to the exact pitch – with an accuracy of ±1 cent, even in noisy environments where conventional clip-on tuners fail.

Benefits

• No more tool switching: Tuning and string changes happen with the same device – you don’t put anything down, don’t grab the wrong tool, and save time during setup.
• No retuning needed: The automatic detection hits each string right away, so you don’t have to adjust multiple times or match the tone manually.
• No failure on stage: The rechargeable 3100 mAh battery with USB-C lasts up to 5 hours – you no longer need to check if the batteries are full before your performance.

Usage

1. Power on: Start the device with the push of a button – the LCD display immediately shows the current mode and battery status.
2. Tune: In auto mode, strike the desired string – the Strummer automatically recognizes it and precisely turns the tuning peg to the target note.
3. String change: Switch to manual mode and use the string winder function to quickly unwind old strings and wind new ones.

Pro tip: Activate the integrated metronome while tuning to calibrate your timing at the same time – so you’re ready to play right after setup without needing a second device.
