This is a volume pedal with smooth operability. You can freely control the volume with the pedal, and the robust housing ensures long-lasting use. It enhances the expressiveness of guitars and keyboards, and is ideal for breaks and fade-ins. I have been using this until recently, and I have performed a simple operational check. Knowledge is required for use and installation. No claims and no returns are accepted. Please refer to the photos for the condition of the product. This is a used item, so please refrain from bidding if you are extremely sensitive or looking for a condition like new. We will ship within 2-4 days after the bid. Management number: 52
