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 the tuner and the crank. The Strummer combines automatic tuning and an electric string winder in one compact device. Thanks to vibration detection technology, it automatically recognizes each string and turns it to the exact pitch at the push of a button – 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 are done with the same device – you don’t put anything down, don’t grab the wrong tool, and don’t waste time setting up.
• No retuning needed: The automatic detection hits every string on the first try, so you don’t have to adjust multiple times or match the pitch manually.
• No failure on stage: The rechargeable 3100 mAh battery with USB-C lasts up to 5 hours – you no longer have to check if the batteries are full before a performance.

Usage

1. Turn on: Start the device by pressing the button – the LCD display immediately shows the current mode and battery level.
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. Change strings: Switch to manual mode and use the string winder function to quickly unwind old strings and put on new ones.

Pro tip: Activate the built-in 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.
