I have had all the Roland guitar synths. This is the best. Best tracking and best sounds! I would say this is in mint condition but I do have Velcro on the bottom and no original packing or manual.I am having to sell off my studio so please look at my other listings. Below is the description from the Roland website: The Roland GR-55 is a revolution in guitar synthesis, with features never before available in any guitar processor. In terms of speed, it s the fastest ever. It s also the most accurate, thanks to newly developed pitch-detection technology. As for sound, the triple-core generator houses a world-class array of virtual guitars, basses, amps, and synth voices, enabling tones and textures that have never been heard before. Onstage or in the studio, you can instantly access the GR-55 s huge library of ready-to-use sounds, from pop to rock and beyond, with quick-access category buttons. Welcome to a groundbreaking new era in guitar synthesis!
