Bugera G5 Infinium Tube Head Amplifier B-Stock

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, BUGERA proudly presents 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 BUGERA's extremely versatile MORPH EQ for seamlessly sweeping between vintage U.S. and British-style tone. Enhancing the versatility of this do-it-all head, BUGERA's 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 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.

INFINIUM Tube Life Multiplier Technology

Years in the making, BUGERA's 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!

MORPHING - Jump the Atlantic Ocean

BUGERA's 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 G5 INFINIUM gives you the best of both worlds, and all the subtle shades in between.

High-Definition Reverb

Adding to its impressive list of tone-shaping options, the G5 INFINIUM's high-definition Reverb puts the perfect finishing touch to your signature sound. Adjustable via the dedicated control on the front panel, you can finally achieve any sound you desire – from a subtle touch to the cavernous, natural-sounding reverberation of a large arena. 

Power Attenuator and Speaker Emulation - Your Best Tone at Any Volume

The convenient, built-in Power Attenuator allows you to operate the G5 INFINIUM at your choice of 5 Watts, 1 Watt, or even 0.1 of a Watt, so you can get everything from sweet and sassy to maximum tube saturation at any volume level. This amazing feature alone makes the G5 worth its weight in gold! And if you prefer to monitor your tone through headphones, the G5 has you covered with its incredible speaker-emulated output, which allows you to get the vibe and sound of either a 1 x 12 or 4 x 12 cabinet - selectable by you! 

Footswitch and FX Loop Included

You have all the tools you need, right out of the box! BUGERA includes a heavy-duty footswitch for channel and reverb selection to give you easy and convenient control of your tone, right from your pedalboard – allowing your focus to remain on your performance.
