2. Tuning the Ukulele
The LAVA U comes with fluorocarbon strings and high-quality tuners designed for stable tuning. It is recommended to tune the ukulele before each playing session.
- Use an electronic tuner (clip-on or app-based) for accurate tuning.
- Standard ukulele tuning is G-C-E-A (from top string to bottom string when held).
- Gently turn the tuning pegs to adjust the string tension until each string reaches its correct pitch. New strings may require frequent re-tuning initially.
Operating the LAVA U
1. Using FreeBoost Effects
The L2 mini preamp with FreeBoost technology allows you to apply effects like Reverb, Delay, and Chorus without needing an external amplifier. These effects are generated directly by the ukulele's body.
- Turn on the L2 mini preamp by pressing the On/Off button.
- Adjust the desired effect using the control knobs located on the side of the ukulele. One knob typically controls Reverb, while another controls a combination of Chorus and Delay.
- Experiment with different settings to find your preferred sound.
