This is the SILK DRIVE from VOX's VALVENERGY series. It's a popular model from VOX that lets you easily enjoy tube amp sound. Included are the box and instruction manual. As a bonus, I'm also including a stereo cable that allows you to use the LINK function when connecting two VALVENERGY series units, where turning one on automatically turns the other off. However, the stereo cable is a bit dirty, so please let me know after purchase if you don't need it.
