Vintage 1986 Marshall JCM 800 100 watt tube guitar head, model 2203. This head is all original, with no modifications. For a 31-year-old amplifier, it's clean and in great shape. It sounds amazing. In the video I have the volume on 1, it gets better sounding when you crank it up, yet still sounds killer at low volume. For more information call Wayne Guitars 530-872-5123 Wayne guitars dot com
