Purchased on March 9th and only tested once. Selling because the sound doesn't suit my needs. As the photos show, it's practically new, but it is still a used item, so please refrain from purchasing if you are looking for a perfect product. Of course, all parts function perfectly, and all accessories are included. Please purchase only if you understand that this is a used item and agree to a no-claims, no-returns transaction.
