Rich tube tone in a size that works from the bedroom to the stage.
The timeless design and sound of the all-tube amp has made its indelible mark on countless beloved tracks spanning the history of the electric guitar. With the ultimate pursuit of those wonderfully saturated, vintage and modern tones in mind, we proudly present the G20 INFINIUM.
Sporting a gorgeous modern look and feel, the G20 serves up 20 beautiful, tube-soaked, Class-A Watts in vintage, as well as modern flavors. With two preamp tube stages for Clean and two dedicated tube stages for Overdrive, the G20 covers vast sonic territories with remarkable ease. Additionally, the G20 INFINIUM features an integrated high-definition Reverb and our extremely versatile MORPH EQ for seamlessly sweeping between vintage U.S. and British-style tone. Enhancing the versatility of this do-it-all head, our revolutionary INFINIUM Tube Life Multiplier Technology makes tube replacement incredibly simple – so you can spend more time playing your music.
Classic Push-Pull Design
The G20 INFINIUM features a true Class-A amp head with a 2 x ECC83 front-end and 2 x EL34 power stage. A masterfully crafted push-pull tube amp, the G20 provides sweetly-balanced harmonics and natural tube compression – resulting in the warm distortion and break-up you’ve come to appreciate from the vintage megaliths of yesteryear – only in a much more portable and attractive package.
INFINIUM Tube Life Multiplier Technology
Years in the making, our INFINIUM Tube Life Multiplier Technology can extend the usable lifespan of your amplifier’s expensive power tubes by up to 20 times, saving you huge money and ensuring the integrity of your tone. How? This revolutionary circuit automatically and continuously monitors the performance of each output tube, and dynamically drives it towards the target operating point, for an evenly distributed load.
INFINIUM also compensates for the effects of aging, automatically adjusting current levels to keep your tubes sounding as good as new – even when AC line voltages drop below nominal levels. Similar technology has been used for decades in all-wheel drive cars, where systems modulate the power going to each wheel to improve traction. Just consider INFINIUM Series amps “4-wheel drive” for your guitar.
INFINIUM Series amps take all the guesswork out of tube replacement by illuminating an LED next to a tube that is reaching the end of its usable lifespan. And thanks to INFINIUM’s Auto-Bias design, you simply replace the indicated tube – without a trip to the repair shop, saving you even more money.
MORPHING - Jump the Atlantic Ocean
Our proprietary MORPH EQ control lets you instantly jump the Atlantic Ocean, to give your music either classic U.S. or British-style EQ tone – or anything in between! Why choose between two great sounds? The G20 INFINIUM gives you the best of both worlds, and all the subtle shades in between.
