MOSKYAUDIO BLACK JUICE Guitar Preamp Overdrive Effects Pedal Gain/Mid Boost/Volume/Treble/Bass/4-Mode Knob DC 9V 6.35mm Input/Output Interface Electric Guitar Preamp Overdrive Effector with True Bypass Features: 【Enhanced BB Circuitry】: This guitar pedal takes the original BB circuitry and adds a Mids dial, essentially providing a three-band EQ. We've added mid-high control to the pedal, giving your sound a more aggressive "punch" and offering up to +12dB of mid-high boost. 【Versatile Controls】: The pedal features a Gain control knob, Mid Boost knob, and Volume knob, along with a two-band EQ for Treble and Bass. The Bass Boost knob adds extra low-end warmth to the signal without becoming muddy, while the Treble Boost knob adds extra high-end sparkle and shine without becoming too brittle. 【Mid Dial】: The Mid Dial can boost the volume by up to 12 decibels. When rolled to around nine o'clock, it should be set in a neutral position, allowing all tones of the original BB preamp to be played.  【4-Mode Selection Knob】: The pedal features a 4-mode selection knob, offering a voicing switch for versatile sound shaping. This allows you to tailor your sound to suit your playing style and the genre of music you're playing. 【True Bypass】: The pedal features true bypass switching, preserving the integrity of your signal when the pedal is not in use. It requires a DC 9V power supply with a negative center, ensuring easy integration into your existing pedalboard setup.
