This is the HA-7 AC adapter for powering effects pedals. It's a type that can supply power to multiple effects pedals from a single adapter, and it has four output jacks. It's a convenient model for consolidating the power supply on your pedalboard. I used it at home. I've confirmed that it powers on, and there are no issues with its use. The exterior is in relatively good condition, but there may be minor scratches due to it being a used item.
