Volume Up, Volume Down. Boost potentiometer: passive pickups. Charge Indicator: Indicates charging status. Charging port: facilitates charging of built-in devices. Headphone Jack: Allows direct connection of headphones for private playing. Distortion switching: Provides a variety of distortion effects. Counterclockwise left: Reverb effect. Clockwise center: Chorus effect. Clockwise right: Delay effect. Press the potentiometer: Turn on the Bluetooth function (YX-MUSIC). Indicator Lights: Red light indicates that charging is required, blue light indicates Bluetooth connection. Pre-wiring kit: the guard is equipped with the necessary electronic components, already pre-installed and connected to simplify the installation process. Humbucking Pickups: This kit includes humbucking pickups, which typically offer higher output and different tonal characteristics than common single-coil pickups. Built-in effects: The guard has a variety of built-in effects to enhance the versatility of your guitar. Time effects (time-based effects). Reverb: Simulates sound reflections in different environments, adding depth and dimension to the tone. Delay Effect: Delays the input signal for a period of time and then outputs it, creating an echo effect that adds a sense of space and richness to the tone. CHORUS EFFECT: Mixes the original signal with a slightly delayed copy to create a rich and expansive timbre. Phase effect: Changes the phase of the input signal to produce a flowing timbre. Vibrato effect: Quickly change the volume to produce a vibrato effect. Distortion: Increases the distortion or compression of the audio signal to produce the characteristic tones of rock, metal, and other musical styles. Overload: “overloads” the signal before it is amplified, increasing volume and distortion to create warm orchestral tones. Blur: Adds extremely rich distortion to produce heavy, harsh tones.

Volume Up, Volume Down/2. Counterclockwise leftmost: reverb, 2. Clockwise center: chorus, 3. Press the potentiometer: turn on the Bluetooth function (YX-MUSIC). Indicator light (red light on when need to charge / blue light on when connecting Bluetooth). Pre-wired kit: the guard comes with the necessary electronics pre-installed and already connected, simplifying the installation process. Humbucking Pickups: The kit includes humbucking pickups, which typically offer higher output and different tonal characteristics than the single-coil pickups commonly found in Stratocaster guitars. Built-in effects: The guard has a variety of effects built in to enhance the versatility of the guitar. 3.1 Timing effects (time-based effects). Reverb: Simulates sound reflections in different environments, adding depth and dimension to the tone. Delay effect (Delay): delays the input signal for a period of time after the output to produce an echo effect, adding a sense of space and richness to the tone. 3.2 Modulation Effects. Chorus effect (Chorus): Mixes the original signal with a slightly delayed copy to create a rich, expansive tone. Phase effect (Phaser): Changes the phase of the input signal to create a flowing tone. Tremolo effect (Tremolo): rapidly changes the volume to create a tremolo effect. Distortion (Distortion): Increase the distortion or compression of the audio signal to produce the characteristic tones of rock, metal and other music styles. Overdrive: “overloads” the signal before it is boosted, increasing volume and distortion to create a warm orchestral sound. Fuzz: Adds extremely rich distortion to create heavy, harsh tones.
