Thank you for viewing. This is a Zoom multi-effects processor, the G1Xon. I originally purchased it from an acquaintance, but I'm selling it because I'm considering replacing my equipment. The surface of the board is relatively clean, but there is rust and dirt on the back. The original power adapter, instruction manual, and effect list (printed from the internet) are included. Please note that although Zoom does not provide software to operate patches from a PC for this product, there is freeware called ToneLib that allows you to manipulate patches via USB. This is convenient for those who want to tweak the sound by modifying the contents of the patches.
