Infinium technology takes the hassle and expense out of tube tone

Sweetwater guitarists agree that there's no tone like tube tone. But we also know that the cost involved in owning and maintaining a tube guitar amplifier can be prohibitive. Solid state amps have come a long way, but even the best amp model can't beat true tube tone. Bugera's Infinium technology means no more compromising what you want. The Infinium circuit is designed to optimize the performance of your output tubes and distribute the load evenly between the tubes, giving you tonal integrity and reliability. By automatically adjusting current levels, aging tubes are compensated for and your tone retains that toasty, day one sound throughout its life. But tubes, by nature, do wear out and die. However, when you play an Infinium amp, you'll never worry. This exclusive technology allows you to grab whatever replacement tube you have on hand and get back to playing - there's no matching necessary. In fact, now you can mix and match tubes to create your very own signature sound without the hassle and expense of buying matched pairs. And because Infinium is a bit like having your own guitar amp tech with you on every gig, you get up to 20 times more life out of your tubes. When it is time to change one out, you'll know exactly where to go thanks to the life-monitoring LED readout that keeps you in the know about your amp's health. Only Bugera makes the joy of owning and playing a tube amplifier this accessible and easy!

Dedicated tone channels make getting the right sound easy

The transparent clean channel doesn't break up, which is great for playing jazz, country, and blues, and it works great as a power base if you're using pedals for your overdrive and distortion tones. The crunch channel gets you to that halfway dirty place you need for rock, and you can use the gain on this channel to pull out your blues and metal rhythm tones. Lean on the lead channel when you need gain, gain, and even more gain than what the crunch channel can give you. The XL switches on the lead and crunch channels offer you extended low end control while the adjustable noise gate on the lead channel gives you even more tonal control. All three of the 333XL Infinium's channels have individual volume controls and an EQ section that lets you really dig in and fine tune your tone, and the master section presence control handles the shaping of your midrange.

Features that give you tremendous versatility

The 333XL Infinium would be awesome as it stands, but Bugera made sure to put options and features at your fingertips that make your playing experience second-to-none. You get an FX loop with adjustable send and return levels that also works as a boost option, allowing you to set all three channels at the same level and control the master volume regardless of what channel you've selected. Each channel is also independently assignable to the reverb for total tone control. If you need to feed the PA or other mixer or interface, there's a line output with a dedicated level control. Variable impedance lets you match your 333XL Infinium to almost any speaker cabinet and switchable power amp damping lets you optimize the resonance of your speakers to polish off your tone. They've even included the footswitch - this amp is a superb value!

Bugera 333XL Infinium All-tube Guitar Amplifier Head Features:
  • Hand-built, 120-watt, Class A/B, all-tube amplifier driven by 4 x EL34 tubes for huge tone
  • 3-channel preamp design - clean, crunch, and lead - features 4 x 12AX7 tubes for superior versatile tone
  • Heavy-duty footswitch for channel selection, FX loop, and reverb included so you can rock straight out of the box
  • Integrated reverb is assignable for each channel to let you get just the sound you want
  • XL switches on lead and crunch channels to give you more low end control

Bugera 333XL Infinium head

Just got through checking out my new 333XL Infinium. I am blown away by it....I have been playing for 40 years and this is the first perfect amp I have ever bought. Youve got clean, crunch, and lead at at your finger tips or I should say foot tips. I owned a 333XL non infinium and this new one sounds even better than the old version. There is not a hint of fizz in the sound. I played it through my Orange PP112 and it has that chunky kind of sound that I normally was able to obtain only through my Marshall 412 cab. If you are in the market for a high power type head do not hesitate to buy one of these, you will not regret it.

Buy this amp

I watched videos all over the net about the BUGERA 333 vs this amp or that amp. This amp has a sound that WILL blow away any mesa boogie, engle, h&k. It has a solid low punchy bottom and chimney clean tones, add in a sonic maximizer and a decimator noise gate, and the metal world will be ENVIOUS.....im a boogie guy. Mk5 to be exact....no more, so long g high priced b.s. BUGERA IS HERE TO STAY.

Amazing Tube Amp!

The research and videos on how this amp was manufactured and how it sounded did not do enough justice to it then it did in person. Once I took it out of the packaging box, I was immediately blown away on how well built this head is. After plugging everything in and played raw straight from my PRS baritone, I was immediately astonished by the sound it gave me. It's honestly the sound I've been dreaming for. I was even more surprised on the clean channel in which delivers a warm yet, perfect sound presence that accompanies my style of playing. Overall, this amp is perfect for those who wish to save a few extra cash. This buy was worth it and the sound was like no other! Well done Bugera!
