This is the BOSS Acoustic Simulator AC-3. I am selling it because I am not using it. The manufacturing date appears to be June 2008. I have confirmed that it works and can be used without any problems. This is a player's condition item, so please refrain from purchasing if you are concerned. Also, to prevent any trouble, I request no returns or refunds. - Model: AC-3 - Brand: BOSS - Type: Acoustic Simulator - Input Terminals: INPUT - Output Terminals: G.AMP OUT
