Samson does lots of business with a very large consumer electronics dealer and they just sold us al of their consumer returns and overstock items. We test each item as we get it and sell it as an Open Box item for way below the usual Retail price. This is one of those items. The packaging is not perfect but the bass head is fully tested and is working as new and it is covered by a 30 day warranty from Butler Music. As you can see it does have a few scratches on the left side.  Save big on a new item that has been fully tested and is ready to go.
