I didn't want to bring in an amp, so I bought this to easily add distortion. However, I only used it a few times and then stored it away. The item for sale is the main unit only. Operation has been confirmed. There are some minor scratches, but it's in overall good condition. It has an American, high-gain sound, with a tone that has a strong presence whether used for solos or rhythm. It's perfect for a lightweight pedalboard. Please consider this item with the understanding that it is a used product.
