This is the older model of the One Control Sonic Blue Twanger. Everything in the pictures is included. I purchased this new from a musical instrument store several years ago. I've used it a few times, but I'm selling it to declutter. There is rust and dullness on the button on the front, and some scratches. There are multiple small scratches on the main unit (please refer to the photos). Overall, it appears to be relatively clean. I have confirmed that it works, and there are no problems. This is a used item and has been stored by a private individual, so please refrain from purchasing if you are sensitive to this. To prevent swapping, please understand that no returns or refunds are accepted. Type... Electric Guitar
