World Music Supply | Bugera Infinium Technology


Within the world of electric guitar, the tube amplifier is the almighty, unchallengeable king of tone. Capable of producing everything from clean sounds that are beautifully articulate while at the same time it can go all the way to the most degenerate overdriven tones that breathe with warm harmonics, string definition and clarity. from the beginning, its been the same, tube amps have ruled the world. Opinions as to exactly what great tone is, have evolved over the years but through it all one thing has remained constant; solid state, no matter how advanced modeling gets, no matter how good computers can replicate the sound, it just can’t compete, and you don’t have to be a tube amp purist to know that solid state will likely never be able to match the warmth, or breadth of tones as the venerable vacuum tube in most audio applications.

 For the past three quarters of a century, tube amps have constantly been a source of headaches to guitarists worldwide, as they are just so frustrating to own and operate. Cost of ownership includes both regular maintenance items like replacing tired old tubes and rebiasing as well as the occasional repair bill, often due to a tube’s lifespan being unexpectedly shortened because they tend to be so very fragile. I mean lets be honest, one good jolt to the chassis while moving an amp before its tubes have had a chance to cool down, is just asking for trouble.  As most of us dedicated guitarists will do anything for our sound, we have typically shrugged these issues off with little drama because we all know that great tube tone is worth almost any amount of extra effort. Swapping out tubes once or twice a year (more often for some of us) and having our amps rebiased seemed a small price to pay. Of course it also gives our friendly neighborhood amp techs a reason to get up in the morning.

Rejoice Tube Fans! The days of expensive maintenance issues and annoying and untimely gear failures may be forever behind us. Enter Bugera Amplification with their Infinium Valve Life Multiplier Technology. The good folks at Bugera have been hard at work engineering ways to make our lives as tube amp aficionados both easier and less expensive. How would you like to be able to indulge in all of your favorite tube tones without ever having to worry about failing valves or rebiasing? Now throw in tube life that averages 20 times longer than normal. Sound too good to be true? Well guess what, it’s not.

Years and years of R&D have produced the revolutionary new Infinium technology. Automatic and continual monitoring of each individual power tube gives you ample warning before a tube has the chance to dramatically affect your tone, or worse yet, ruining your performance. This is accomplished via the Valve Life Monitoring indicator on the back panel of the amp. Any upcoming valve failure will trigger a bright red LED next to the corresponding tube.

In addition to making sure you get through your bands set without equipment failures, Infinium also continually monitors for optimal tube performance. The system automatically keeps an eye on operating conditions and tweaks for top notch tone. For instance, current levels are monitored and adjusted automatically, all to keep your tubes sounding great,  even if line voltage drops below optimal levels, so no more of that annoying tone “suck” that happens from time to time.

Biasing is also handled automatically with Infinium. Just swap out a tube and the system automatically takes care of it for you. No more trying to do it yourself, risking the lives of you and your amplifier, and definitly no more expensive visits to an amp tech. So you can save those guys for serious problems instead.

Also, how’s this for a neat trick? So your Infinium just informed you that one of your EL34’s is about to go and you only have a 6L6 available on you? No problem. Out with the EL34, in with the 6L6, or 5881, or 6550, heck, just about any tube will do the job! Replace it later with the “correct” tube or enjoy the tone crafting ability of being able to run the amp on which ever odd tube you would like! 

Never again replace an entire set of tubes because your amp suffered a serious jolt right before a show. Never again throw the power switch on your amp and find it dead because it was loaded out at the last gig while the tubes were still too hot.

In fact, most of the issues that used to cause us undue expense and stress have been addressed and promptly, eliminated by Bugera’s Infinium Technology. Since the company’s extensive lineup of amplifiers covers just about every musical style from classic rock to ultra modern metal, there is sure to be at least one model that suits your needs perfectly. Take a long, hard look at Bugera’s complete line of Infinium equipped amps at today!
