- Model: BOSS GT-1 - Accessories: AC adapter - Connections: MIDI terminals - Functions: Multi-effects processor Thank you for viewing. I am selling this item as I no longer use it. I purchased it six months ago and have only used it at home. The unit has been tested and is in good working condition with only a few scratches. I will also include a Vital Audio power supply. This has also been tested and is in working condition, but please note that it does not come with a DC cable. Please be aware that this is a used item, so please refrain from purchasing if you are overly concerned about its condition. Thank you for your understanding.
