The 4th edition of Blue Book of Guitar Amplifiers contains the entire contents of the 752-page book as well as over 3,000 color images. The CD-ROM also includes the Photo Grading System, as well as many .pdf files including Amp Dating Tools and House Brand information. This CD-ROM works through most web-based browsers. To find an amp, simply locate the letter of manufacturer (A-Z), the manufacturer (Fender, Marshall, Gibson, Ampeg, etc.), and select from the list of categories that appear under the manufacturer. Several models have one or more pictures that makes identifying amps a breeze!
