Used in a recording studio, but I am listing it for a limited time to secure funds for the introduction of new equipment. It has never been taken out, and I have used it in a rack since purchase, so there aren't any major scratches, but there are some minor scratches and dirt. Also, there is some crackling in the switches, but it wasn't a problem once the settings were decided. Regarding the MOD content: The output transformer, amplifier card, and other parts have been MODded. Basically, no claims and no returns are accepted except in the case of no power. I am also listing it on another site. Please note that it may be cheaper there due to fees, etc.
