Bugera G5 INFINIUM Amplifier Head

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 G5 INFINIUM.

Sporting a gorgeous modern look and feel, the G5 serves up 5 beautiful, tube soaked, Class-A Watts in vintage, as well as modern flavors. Additionally, the G5 INFINIUM features an integrated high definition Reverb; a built-in 2-way Power Attenuator, so you can achieve the ultimate sound at any volume, 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.

The G5 INFINIUM features a true Class-A amp head with an ECC83 front-end and a 12BH7 power stage. A masterfully crafted push-pull tube amp, the G5 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.

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.

Available exclusively from BUGERA, INFINIUM Tube Life Multiplier Technology is a major breakthrough in amplifier design and manufacture, providing incredible reliability for your stage performance and more consistent sound over the lifespan of your tubes. Since they are always operating at optimal levels, your output tubes perform more predictably and last much longer, thanks to BUGERA’s marvelous INFINIUM Technology, saving you some serious money!
