CONGRATULATIONS ON YOUR NEW
GIBSON HANDBUILT SERIES AMPLIFIER
As the new owner of a Gibson amplifier, you have joined a great Gibson legacy. When the
electric guitar emerged in the 1930s as an instrument with its own voice, Gibson amplifiers
powered that voice. In the 1940s and 1950s, Gibson’s continuing advances in amplifier design
matched the company’s celebrated guitar innovations. Over 60 years later, in 2004, Gibson
Labs introduced its most prestigious range of amplifiers to date; the Gibson Handbuilt Series.
Each Handbuilt amplifier represents an uncompromised approach, from design to manufacture.
From the all-tube circuit path, to the meticulously hand-wired turret board, every aspect
of your new amplifier has been brought to you with no less a mission than to build the very
best in professional amplification. Built into every Gibson Handbuilt amplifier is a respect
for the simplicity that creates long-lasting, superior tone. You’ll hear it in the natural
responsiveness to your play, the rich tone and see it in the top quality cabinetry, tolex
and overall attention to detail.

We invite you to plug in, turn up, express yourself and become a part of a great Gibson
tradition.
If you ever have a question or concern about anything, any day, any time, please call Gibson
Customer Service at 1-800-4GIBSON (444-2766) or email ser[email protected].
