INFINIUM Valve Life Multiplier Technology
Our revolutionary INFINIUM Valve Life Multiplier technology is like having your very own technician inside your amp constantly monitoring and tweaking valve performance for the ultimate in tonal integrity and reliability. This revolutionary circuit not only optimizes the performance of each output tube, it dynamically balances the drive between them to more evenly distribute the load. With INFINIUM, your tubes last up to 20 times longer, saving you substantial money over the lifespan of your amplifier. INFINIUM also compensates for the effects of aging, automatically adjusting current levels to keep your valves sounding as good as the day they were installed.

If and when a valve does reach the end of its life, the system even tells you which one to replace. All you need do is replace the faulty valve and let INFINIUM take care of the rest for you. This all adds up to more consistent sound quality and longer life for your valves. Maintenance for valve amps has never been this easy!

Noise Gate on Lead channel
This is an ANALOGUE gate that will never close or shut you off in a clean passage. It is designed to decrease high frequency noise and hiss without changing your tone and it works loads better than a lot of competitors’ gates.

XL switch on Crunch and Lead channels
The XL function will add more chunk to your sound. You can add some thunder to the combo version to more closely emulate a 412 cab, thicken the sound of single coil pickups or add sustain to single-note melodic passages.

Three fully independent channels
A totally Clean channel that won’t break up; a Crunch channel for a halfway dirty rock and blues tone (or crank the gain for a metal rhythm tone); and a Lead channel with the same structure as the Crunch channel, but with access to more gain. Each of these channels has its own volume feeding the overall master volume, giving you total control over the level of each.

What is your opinion of this product?
1st tube amp that i have owned, so far it has work flawlessly. Each channel has its own eq and volume so you can dial in each channel as you like, and the master volume control keeps it level for all channels.

Read all reviews. For the Price best deal at American
What is your opinion of this product?
I own a B-52 100 watt solid state amp head and a Black Star 100 watt tube amp head. The Bugera has much better sound, highs and lows, especially playing metal. Its exotic looking and "kicks ass". All I can say is crank it up and Rocks still lives here in Georgia.

In your face awsome!!!
Your general opinion of this product.
This amp is a beast , the sound is just a smash mouth distortion with ultra clean tones very surprising and very comparable to many other brands I've played over many years.
This product is very well made and super dependable.
The sounds are heavy , chunky , and clean . If you purchase this awsome amp you will love it.
I've only had it a week but I took and used it at a gig instead of taking my Marshall JCM800 and this thing delivers so I know it will stand the test of time and be very reliable.

Perfect
Your general opinion of this product.
This amp does everything I need: Great cleans, a Marshall-esque Crunch channel, and a nice modern Mesa-ish Lead channel. I have done away with all of my dirt pedals and my EQ and noise gate with this amp, as I feel they are no longer needed.
Although I have heard some horror stories, I have had zero problems so far.
This amp feels very solid. The Tolex is very nice, and the chassis is nice and heavy.
The stock tubes were fine, but I did decide to swap out a couple of the power tubes for some 6L6s, and I have a vintage RCA 12AU7 in the PA position. I also installed Tung Sol reissue 12AX7s in the preamp section. The mix of the 6L6s and EL34s seems to be a happy medium for the US vs British sound. The Tung Sols seem to smooth out the fizz in the overdrive.
The action was go.
No stains yet. ;)
So far, so good.

Amazing Amp, full of tone options.
Your general opinion of this product.
Good clean channel, and great crunch and lead channels. This amp sounds so mean. I match up with celestion v30's and maxon 808OD. For the tone, features, and power, the price is a steal.
I own several Bugera Amps, have had a few issues that were resolved.
Tons of tonal variety.
Warranty for 3 years.

yes,I had it for 4 YRs without a hitch and sounding better with brackin times applying from mellow to so hard sounds seam to come easy with this head!
just say you heard it you can play it all styles sound well!
real real good sounding head for price,leans toward clear blues and hot rock styles but will play smooth Jazz.

One of the best tube amps I have owned.
This thing is built to last.
Mine has never given me a moment to worry about.
Your general opinion of this product.
This is a well made, well designed amp. I would recommend it to anyone who wants a great tube amp at a budget price.
The controls are well laid out and set up is easy.
This amp covers it all. With 3 channels you can get what ever tone you are looking for. The clean channel is near perfection.
The coverings accent with the grill front looks like this amp means business. Metal corner covers also add great protection and add to the look.
Played well right out of the box.
