The Boss BD-2 Blues Driver is a pedal that offers overdriven tones from creamy leads to crunchy rhythm sounds. It can faithfully express the tone change caused by moving the knobs on the guitar. Furthermore, it can create distortion that can faithfully reproduce the picking nuance of the player. You can achieve a wide variety of distortions from crunch to hard distortion, by adjusting the Gain Knob.
The BD-2 is a popular pedal that provides drive ranging from warm overdrive to emotive distortion that responds both to your playing style and dynamics, similar to the responsiveness and tone of a vintage vacuum tube amplifier.
The BD-2 offer three tone-shaping controls for you to introduce into the blues genre. The LEVEL knob adjusts the volume of the effect sound. When turning the LEVEL knob counterclockwise threshold you will hear no sound. The TONE knob allows you to adjust the tone of your sound. Rotating it clockwise will create a sharp sound with emphasized treble. While turning it counterclockwise will create a soft sound with a cut to the treble. Finally, the BD-2 offers a GAIN knob that lets you adjust the gain of the blues driver. By rotating the knob clockwise it will increase the gain creating harder distortion.
The INPUT jack on the BD-2 will accepts input signals (coming from a guitar, some other musical instrument, or another effects unit). The INPUT jack also serves as the power switch. This means that the power is turned ON when you insert a cable into the input jack. It is then turned OFF when a cable has been removed.
