This is an overdrive pedal that achieves an amp-like drive sound. With three knobs for Drive, Tone, and Level, it's easy to set up. Its characteristic of boosting the mid-range while cutting the low-end prevents your guitar's sound from getting lost in the mix. It's a classic, popular in a wide range of genres like blues, rock, and fusion, with numerous clones and modified models available. 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 accepted. 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: 25
