ZOOM Multi-Effects Processor A1 A1X FOUR For sale. Purchased new about a month ago and used with a trumpet. I only used it for testing, and while it was fun to create different sounds, it has too many functions for me to use properly. I put it back in the box and stored it away. There are some minor scratches on the LCD screen, but it's almost like new and should still be usable. All original accessories from when it was new are included. Product registration has not been done yet. It's useful as an effects processor for wind instruments and vocals. A separately sold AC adapter is also included. - Model: A1 FOUR/A1X FOUR - Type: Multi-Effect Processor - Accessories: AC Adapter - Display: LCD Display
