Guitar phaser effect pedal. I purchased this on May 26, 2025, but I had no opportunity to use it because the event I planned to use it at was canceled immediately after purchase. Therefore, I am selling it. I tested it and it produced sound without any problems. I have only used it to test the sound after purchase, and have stored it since then. 【High-Quality Sound】 The Behringer PH9 is a guitar phaser effect pedal that provides professional sound quality.
