This is a "POD HD500" from "LINE 6". The items included are the main unit, power adapter, power conversion adapter, USB cable, instruction manual and other paper documents, original box. I occasionally used it for line recording indoors. I don't think I ever used it outside, such as for live performances. The frequency of use was quite low. I purchased another multi-effects unit in 2020, so I have kept this unit in storage since then. I am selling it to organize my equipment, as it has increased. In preparation for the sale, I have confirmed that the switches and knobs are working without any problems. I have also checked the operation of the main XLR, phone, and headphone outputs where possible. There may be some minor scratches, but it was originally built to be robust, and I don't think there are any major dents. The protective seal from when I purchased it is still barely on the display. I mostly connected it to a Mac and set up the tones with the editor, so I haven't touched the panel controls on the unit very often. In preparation for the sale, I confirmed that it still works with the latest version of the dedicated editor. Also, the unit's system is up to date. To use the editor, you will need to create a LINE 6 account, register this unit as a user, download the editor and other software, and have it recognized by your computer. The editor is also distributed for Windows users. Please check the manufacturer's website for detailed specifications. I think the condition is good for its age, but it is still a used item, so please check the condition in the photos. When shipping, I plan to pack it with air padding over the original box. Thank you for your consideration.
