[Powerful Booster Pedal]: This mini guitar effects pedal provides a 20db+ clean boost with 15db 2 band EQ, creating a rich distortion sound that enhances the original-tone of your guitar. It's perfect for musicians looking to add a powerful punch to their performance. [Adjustable Treble Knob]: The treble knob allows you to adjust the intermediate and high frequencies, making your sound more penetrating and increasing the booster. This feature gives you the flexibility to customize your sound to suit your musical style. [Gain Control]: With the gain knob, you can adjust the degree of distortion. Turning it clockwise increases the distortion while maintaining the clarity of the guitar notes. This feature allows you to create a wide range of sounds, from a subtle crunch to a heavy distortion. [True Bypass Switch]: The true bypass switch provides a transparent tone, ensuring that your signal passes through the pedal unaltered when the effect is disengaged.
