## Description

Product Description This is a great 3 in 1 metronome + tuner + tone generator. Whatever instrument you have, guitar, bass, ukulele, violin, it will help you get tuned in a second. If you have other stringed instruments like banjo, mandolin etc, you can also tune it with the Chromatic mode! You can tune your guitar or bass flat up to 4 semi-tones. Plug in or use the built-in Mic to start to tune. Multiple rhythms take this metronome to a higher level. Train your ear to A4 with the tone generator. Check out the Tone Generator range: A2 – A6. 3 Ways of tuning for your choice 1. Connect a 6.35mm instrument cable to the “input” jack of this product, turn on the product and you are ready to tune your musical instrument. 2. Use the included pick up to clip on the head-stock of your musical instruments, pluck the strings and you are ready to tune. 3. If you are in a very quiet environment, you can use the built-in microphone to tune. Just place the product next to your musical instrument, pluck the strings and start tuning! Tuner： ● Tuning range: A0 (27.5Hz) ~ C8 (4186Hz) ● Tuning modes: Chromatic, Guitar, Bass, Violin, Ukulele C ● Tuning precision: ±1 Cent ● A4 range: 430 ~ 450Hz ● Response time: <20ms ● Flat tuning for guitar /bass: N/A,b, bb, bb, bbbb ● Tuning method: Line-in cable, clip-on pickup or built-in mic For beginners, pls note: Tuner is designed to recognize the instrument's sound frequency and tell you the current note. Accordingly you loosen or tighten the string until the right note shows on the screen. (For example, if you choose "guitar" mode to tune the 5th string of your guitar and the screen shows 4D, means the current note is sharp, loose the string until 5A in green color ). Metronome This electric metronome supports 10 beats and 8 rhythms with a precision of + 0.3%. Set your desired beats per minutes (BPM) from 30 to 250 and practice at your own speed. The volume controller on the top can adjust the volume according to your needs. In addition, you can connect your headphone or earphone to the 3.5mm jack to immense yourself in a pleasant music journey, without distractions from the surrounding environment. This allows you to focus solely on your performance, whether you're practicing at home, in a studio, or on stage.
