Need to sell 4 month old Hartke 3500. It's been in a rack for 3 months and in the box in a closet the last month. Perfect looking and sounding. Has an extended waranty as well. Make a fair offer, this amp is selling used for $420 at the local Sam Ash and retails for $600 ++. If your interested I can send pics I just took of the amp showing the prestine condition.
