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 service@gibson. com. From the Gibson Tone Team at Gibson Labs Technology Group Suite 330 159 South Jackson Street Seattle, WA 98104 www. gibsonamps. com CHANNEL 1 CHANNEL 2 TREMELO Volume Treble Bass Volume Treble Middle Bass Reverb Speed Depth Input Jack 1 Input Jack 2 Mix Input On/Off Play/Standby The GA-20RVT FRONT PANEL Input 1: Accesses the first channel of your amplifier. This is the more aggressive channel that provides less headroom before overdrive. This is the cleaner channel that provides a rich clean tone, breaking into subtle overdrive later, as you increase the channels volume. Mix Input: Unique to the Handbuilt Series, the Mix input allows you to combine the signals of both channels 1 & 2. This is useful for creating a wide range of tonality, mixing clean and overdrive or adding reverb to the overdriven tone of Channel 1. Note: Channel selection and the mix input can be accessed and toggled between with any A-B-Y pedal available at most musical instrument dealers. Reverb: Your amplifier's spring reverb unit is "live" on Channel 2, but can affect Channel 1 via the Mix input. The Handbuilt Series features Tube-Driven Reverb for a more natural, smoother reverb effect. A clockwise turn increases the reverb "tail;" a counter clockwise turn decreases the reverb tail. Tremolo: Creates an intermittent signal effect (think surf music) with variable Speed and Depth Controls. We recommend that you have your "Play/Standby" switch in the "Standby" position when powering up. Play/Standby: Allows you to idle your amplifier in "Standby" mode (no signal output) or Play your amplifier in "Play" mode (signal output). REAR PANEL Footswitch: Accepts the 2 button footswitch that shipped with your amplifier. [. . . ] To check the line voltage setting, note the voltage setting visible through the window in the power line fuse compartment cover on the back of the amp. To change the line voltage setting: 1. Disconnect the power by removing the power cord from both the power outlet and the amplifier. Open the fuse compartment by inserting a screwdriver blade gently into the tab at the bottom of the compartment and prying until the tab can be removed with the fingers. Remove the line voltage selector assembly by gripping the line voltage indicator tab with pliers and pulling it straight out of its connector. [. . . ]
