Used BOSS SX-700 unit and AC adapter BRC-100T. This unit is convenient for easily selecting and using spatial effects like reverb and chorus. I was using it as a spatial effect connected to the mixer's send return until recently. Therefore, I have confirmed its operation regarding line connections. I haven't been able to confirm MIDI functionality due to lack of a suitable environment. It's an old item, so please check the photos for wear and scratches and make your judgment. Photos: 13th photo, a tab is broken. The AC adapter BRC-100T is especially rare, I think.
