This is a booster pedal that, while simple, adds depth and presence to your sound. It offers a wide range of boost, from clean boost to light overdrive, and effectively pushes your amp and other effects. It's useful for boosting volume during solos and for tone correction. I was using this until recently, and I've performed a basic operational check. Knowledge is required for use and installation. No claims and no returns. Please see the photos for the product's condition. This is a used item, so please refrain from bidding if you are extremely sensitive to condition or are looking for a new-like condition. We will ship within 2-4 days after the bid. Management number: 31
