This Positive Grid Spark 40 is the original model, purchased the year after it first came out, used sporadically and carefully for about a year, and since then it has been on the shelf as I found the Positive Grid Spark Mini is all the volume I need. It is an excellent Bluetooth speaker for music as well a great guitar amp. The unit functions like new and has had its firmware updated once. With the amp itself, I am including all originally included parts, such as the leather carry strap, the AC adapter, and the USB cable. On top of that, I'm throwing in the carry case that normally you would buy separately. The app that works with this amp is free at the Play and Apple stores. The amp will be shipped in its original Positive Grid box.
