An amp primed to get the most out of either acoustic or electric guitars.

The Gibson GA42RVT combo amp surpasses many dedicated acoustic tube amps on the market. Hand-wired, this guitar amp features a 30W pentode/triode Class A, 12" speaker, with 2 channels and a "Mix" input. Part of the hand-built range, the Limited Edition GA40RVT delivers exceptional tone within a meaningful compliment of boutique features.

The tube-driven reverb gives a deep, full tone that comes through with full clarity, offering ideal tones for indie and alternative rock sounds. The tremolo pulses through your body, giving depth to your tone. Two-tone vintage brown and cream Tolex adds that classic vintage look and feel. Thanks to Gibson's impeccable craftsmanship, this tube amp is primed for acoustic or electric, whether in your studio or on the stage.

Input 1: Accesses the first channel of your Gibson amplifier. This is the more aggressive channel that provides less headroom before overdrive. This channel offers Treble and Bass Controls.

Input 2: Accesses the second channel of your amplifier. This is the cleaner channel that provides a rich clean tone, breaking into subtle overdrive later, as you increase the channel's 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.

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. At 7 o'clock, the Reverb effect is off.

Tremolo: Creates an intermittent signal effect (think surf music) with variable Speed and Depth Controls.

Speed: Determines the rate at which the signal fluctuates in volume.

Depth: Determines the subtly or severity of the signal fluctuation.

On/Off: Turns your amplifier on or off. We recommend that you have your "Play/Standby" switch in the "Standby" position when powering up. This helps preserve tube life.

Play/Standby: Allows you to idle your guitar amplifier in "Standby" mode (no signal output) or Play your amplifier in "Play" mode (signal output).

Footswitch: Accepts the 2 button footswitch that shipped with your amplifier. Reverb and Tremolo are turned on or off with these buttons.

Pentode/Triode Switch: In Pentode Mode, your amplifier will run in full power, providing higher output. In Triode Mode, your amplifier will run at about 1/2 power. This feature further enhances the flexibility of the Handbuilt Series. With it, you essentially have two amplifiers. For classic to modern rock styles, the high power output will perform with a more aggressive overdrive. In low power, Jazz and Blues styles benefit from more reaction to your playing attack, allowing you to "squeeze" overdrive out or maintain a thick "punch."

Not the Best Out There.

By Anonymous

from Undisclosed

I have had 2 Gipson amps, the GA40, and the GA42.The 40 just quit, Gipson repaired it, lasted 1 week..They gave me the newer GA42, it lasted 7 months, and quit working. again Gipson repaired it, and today its acting up again. Shuting down for no known reason. I Replace both power tubes,still doing it...Very Disapppoionted in Gipson Amps to say the least. Makes a great sound when its working..

Potentially Incredible Amp

By Zachariah

from NYC

I first began with the 15 watt version, GA20RVT and quickly learned that even though it is beautiful hand wired, point-to-point, it still needed some tweaking. I swapped the tubes and through in a Celestion Blue and WOW! Like night and day! I sold that amp and upgraded to the 2x12 30watt version, GA42RVT. Again, I made my adjustments. First I pulled the 6L6 stock tubes and through in some SED 6L6GC tubes, I pulled the preamp tubes and threw in some NOS RCA 12ax7 tubes, and then I had the amp removed from the cab and installed in a custom built head cabinet. I now run the amp through a vintage JBL D130F and this amp is straight up 64' Vibroverb!!! Very "fenderish" cleans and reverb and nice break/up overdrive when cranked. It takes a few adjustments, but this thing is a tone monster once it is tweaked. I love mine!
