Premier Guitar is On Location in Chicago, IL, where we visit Specimen Products and the Chicago School of Guitar Making. In this video segment, we take an inside look at their "Tube Amplifier Building Workshop," by featuring clips of students working in the lab, first-hand testimonial and finished product demos that are said to be based on old Fender Tweed Champ and 18-watt Marshall circuits. As the video illustrates, each student is given a workstation, all necessary tools and amp kits provided by Mojo Music.
