Complete with a high-definition reverb switchable Class A/AB operation, the T50 Infinium is a does-it-all guitar amp. On top of that, Bugera's Tube Life Multiplier Technology ensures that the T50 Infinium guitar amplifier gives you reliability and consistent tone over the lifespan of your tubes.

Classic all-tube design provides sweet harmonics and warm distortion

Inside the Bugera T50 Infinium guitar amplifier you'll find four 12AX7 preamp tubes, as well as a pair of EL34 power tubes, giving you iconic all-tube tone. For sonic versatility, you can switch between Class A operation for classic warmth or Class AB for a tighter modern sound.

High-definition reverb puts the finishing touch on your sound

The Bugera T50 Infinium guitar amplifier's high-definition reverb adds a distinctive polish to your sound. Fully adjustable, the T5's reverb can provide you with all sorts of different effects. From subtle ambience to a cavernous, reverberant arena, the T5 can pull it off.

Infinium technology takes the hassle and expense out of tube tone

Sweetwater guitarists agree that it's hard to beat real tube tone. But we also know that the cost involved in owning and maintaining a tube guitar amplifier can be prohibitive. Bugera's 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. Tubes, by nature, do wear out and die, but 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.

Bugera T50 Infinium Guitar Amplifier Features:
  • 12AX7 preamp tubes and EL34 power tubes provide sweet harmonics and warm distortion
  • 2-channel design has you covered from cleans and crunch to full-on distortion
  • Infinium Tube Life Multiplier technology extends the lifespan of your tubes
  • Individual tone controls (Bass, Mid, Treble) for each channel
  • Speaker-emulated direct output for sending your tone directly to a PA or recording system
  • Integrated high-definition reverb with dedicated reverb control
  • Footswitch included for channel switching and FX loop

Good value

So, the clean is beautiful, the crunch is nice, the super high gain was...... disappointing..... at least for the first 20 hours of use. I bought two of them, to run a stereo rig. The 2 amps ran about $. 2 Marshall's or Peavey 6505s would have been WAY more than I wanted to spend. After hearing the fizzy high gain sound, I was gonna go ahead and get the Peavey amps. But... was forced to put about 40 hours on them. Oddly enough, in the meantime the fizz has gone away. I can't explain it. It's the same for both heads. Is it possible there is a "break in " period for the components? Anyhow, I'll he keeping them now. They are a knock off of the Vox Night Train 50 btw. There's some bad info out there in "google land" on these. Mine run through 2 HiWatt 4 12 boxes, loaded with Celestion GT75s from the late 80s, early 90s . The cabs are amazing, so these heads really are getting every opportunity to be amazing. And I do like them. Maybe after a bit more fiddling, I'll fall in love with them. Fingers crossed... but still an amazing value. Hope this helps!

Why no 6 star option?

I've been rocking the T50 infinium for a couple years. I bought it used, and it's all stock as far as I know. (No sign of modification) it has a ton of get up and go played through a 4x12. It's good down to 4 ohms also, so you can safely go full on full stack mode, and melt faces. I initially used it as a clean channel pedal queen. This was because a bunch of tube amplifier elitest, sissies reviewed it, and said "it's clean channel is great!" (Imagine that in my mocking voice) "but the dirty channel sounds absolutely horrible." So I took that at face value. Then one day, I forgot my distortion pedal at home, and decided to use the dreaded built-in distortion. At some point, at practice that day, I realized that I was in love. Never had my tones cut through like that. So the deal is, crank that volume knob to 12:00 at least, gain maxed, no phat switch, set eq settings to your ears content. Oh and just a little of the "tone cut" nob. The problem the other reviewers were having was that they were afraid of the power and didn't crank her up. And the hotter the amp gets, the better the distortion gets. I will attest that, the dirty channel is better for rock, (maybe not metal) than any distortion pedal I have used. At this sale price, I'm seriously thinking about getting another one for a spare. Seriously buy 2 You'll love it.

Worth every penny

It's hard to beat this amp in its price range and even a little higher. Put some JJ tubes in and it will sound like the JCM 900 it's patterned after.
Rated 5/5

Quite happy after a few months

I've had the chance to use this head on a few gigs and daily practice sessions. It makes all of my guitars sound their best. I haven't owned a tube amp for 15 years and I don't remember them sounding this good. Lots shimmer and sparkle on the highs. Big rich sustain. Very nice.

Big happy surprise with this amp!

I've only had this for a few days and I'm very satisfied so far! I've been playing professionally for 50 years and have had loads of amps. Just the Fenders included Super, Twin, Deluxe, Princeton, Blues Jr, and most recently the solid state Champion 40. That last one is just for practice. Of course, the Twin is the gold standard, but it also redefines the phrase, "I have your back."

I really wanted a small tube amp and I considered getting another Deluxe, but there isn't enough headroom for a clean jazz sound, so I started a search. This Bugera T50 sounded good and light enough for me. I have a Raezors Edge 10" speaker cab, which is the best IMO. So I took the leap and bought this Bugera without playing it first. WOW! Right out of the box with everything set flat, it really shined! Messing with the settings has yielded lots of great sounds with my archtops and solid bodies. Really sparkling highs with lots of harmonics, pleasant mids, and tight basses. Fat and warm.

One reason I bought it was the auto-biasing feature. I hated taking my other tube amps in for replacement tubes to be biased. I have a box of tubes and now I can mix and match them. About the power rating: This amp isn't as loud as a Fender 50-watt tube amp, but it's plenty loud for me to play outdoor gigs with 200 people. Bigger than that and I can mic my amp. Heck, Eric Clapton uses a Princeton for even his big concerts!

The gain/lead channel is perfect for blues and groove jazz. Some people complained it was too clean, but it's perfect for jazz, country and blues. What about reliability? Too soon to tell. The build quality seems very good and the thing looks cool. I'll post another review if I have issues. Thank you Sweetwater!
