Behringer AC108 Vintager Combo

Quite versatile, i play a lot of blues/rock and it's perfect for that no mid control though which is a bit strange but i guess it's only a practice amp and no features like reverb or anything like the bigger amps but once again it's only a practice amp. The addition of a preamp tube really sets this amp apart from any other small amp i have used. It was horrible right out of the box but as another reviewer suggested i changed the preamp tube to an electro harmonix tube with lower gain and that's when i really saw that this amp had potential. I play through a 1984 fender squire from japan with USA fender electrics and pickups i also use a USA fender strat i built from ebay. When i had the stock tube in i could not get a clean tone from my humbuckers it was always broken up when i used the gain but now that tubes been changed i can get nice bright clean tones on the humbucker. my texas specials were never a problem but they sound even better since the tube swap

I would only rate a 5 out of the box felt as i like i wasted my money on a gimmick amp when i first heard it but then i changed the factory tube for an electro harmonix lower gain 12AT7 as opposed to the stock 12AX7 now i rate this amp a ten no question sounds great through the whole range. I have heard others use a 12AU7 tube or 12AY7 but i have not tried these tubes yet although i think anything with a lower gain gives the amp so much more versatility and great clean sound quality.

never had a problem

not used

change the stock tube to a lower gain one and you will be a very happy camper. For the money you just can't beat this thing if you want a tube amp but can't afford it then just get one of these and mod it. You won't be disappointed.

I wanted a basic practice amp for "rock school" I have created at my school where I teach. I also bought a BB Blaster amp at the same time. The Benringer has two channels and a standard 2 band equaliser. What really impressed me was the curves on this beast. Despite its small dimensions it just LOOKED like a PROPER amp (with a nod to the VOX AC30) rather than a cornflake packet. There is a CD input facility as well though I have not used it. The back of the speaker says 20W.

Wow! I wish this had been on the market years ago! The overdrive function on the Blaster was okay and messy, but the Behringer actually sounded musical. You could certainly get that Carlos Santana "smooth" sound and this was with a cheap guitar! My Ibanez GAX30 feels great to play but does not sound very nice through my large Laney. However the ac108 made it sound almost as good as my more expensive Ibanez SAS guitar. Overdrive facilities on practice amps are good at disguising mistakes. This amp really enhances the player's ability. It sounds good clean too.

Foolishly, I accidently dropped it down a staircase. It still sounded fine. The wood feels ever so strong.

No idea.

Of course it would be nice with reverb and a footswitch but Behringer did not make it for experienced players. For a beginner it is a must and the only reason I was moaning is because my larger Laney does not sound as nice as this. Larger Beringer tube amps are so hard to find.

Beginners' amps all look the same. 10W, overdrive, Cd output, and very cheap. This one is NOT a toy, it is a tube amplifier. It just happens to be rather small. It may be a few pounds more than the cheapest on the market but you get more volume and a warm pleasant overdrive all in a cool looking box.

If you are reading this with the aim of buying one, I would say do so. Please note that the amp in the Vintager package has a 15W speaker and not 20W as they would be by themselves. It sounds fine but is not as loud.

you know all the features, 8" speaker, 12ax7 tube, vintage look, cd in, headphone out, etc.

I got this amp because I wanted an amp with a tube in it at the time.

I mostly play metal, hard rock, but now I am getting into country.

I wish this amp had reverb. I hate just a plain signal.

I use this for around the house. I do not play in a band or in public, so I can't comment on its "live" capabilities. for what I use it for it's the tops.

I use all sorts of axes with this. modified squier affinity (dual rails in bridge, singles in neck and middle), squier standard tele, modified esp ltd m-100, vantage les paul, various home made frankensteins.

With each one of these guitars the clean signal from the ss channel is good.

But the tube is where all the fun is to be had. I changed the stock "hand picked" tube to a GT 12ax7 and now this thing has some balls. After I replaced the stock speaker with a Jensen Mod 8-20, it really has some serious cajones. I my opinion after the mods, this is the ideal blues amp.

I've had this amp for years, and used it sporadically. After the mods I have tough playing playing out of another amp, except when I want METAL ...then I go with my reliable Crate gt-80d.

I have never had noise issues, it dying on me, nothing.

never dealt with behringer. I have never had an issue with their products.

After ten years of playing I no longer need to look for another blues amp. I tried all sorts of guitar/pedals/amp combinations looking for a great blues tone. Now no matter what guiatr I play, I can get a kick *** blues sound with this.

It was ~$70 new, and with $30 in mods it is one of my favorite pieces of gear, next to my vantage les paul, and my heavily modified esp ltd m-100 (not fm).

If it was stolen I would absolutely replace this thing with all of the after market parts. You can't understand how good it is until you replace the generic behringer parts.

Hybrid guitar amplifier with 8 inch speaker and 12ax7 pre-amp tube. Two button switchable channels, master and gain volume controls, bass and treble tone-controls, a sort of a mids-emphasis button, CD-player in, headphones out. All the basics for a practice amp.

I use this amp with a 80's Tokai breezysound Telecaster and a 2007 Fender Highway 1 Telecaster. It has a nice clean sound, although low E-string notes tend to sound a bit muffled. I thing the stock speaker (15W) can not handle the attack. With distortion its less of a problem. At higher volumes one notices that the stock speaker can not handle the power. If you only play this amp at low power settings its not a problem. Both the clean and gain sound are very usable. On the basis of an earlier user review i changed the stock speaker for a Jensen C8R (4 ohms), which makes all the difference. The Jensen is 25W and handles bass-tones and attacks much better. It's a huge improvement. The sound-rating is for the stock speaker. With the Jensen i would give it a 9. Still, compared to a 10"-speaker (Frontman 25r) which i also play now and then, the 8" sound is thinner. This is especially evident if i run the drummachine through the amp. But for a practice amp the sound has enough body.

It hasn't broken down on me. It is very well build (MDF-board). The electronics are simple and efficient and except for a tube-change once every few years i'm not expecting any trouble.

No experience. It has a three year warranty (which maybe i voided by replacing the speaker)

I've been playing for 20 years. This is a good investment. I payed 49 euro for the amp and another 42 for the Jensen speaker. For 91 euro this is still a good buy. I love its simplicity, low weight and small dimensions and still the 8" speaker moves a lot of air. It has a very good tone, clean and gain, especially with the speaker upgrade.

Basically a practice amp, one input switchable bewteen a fixed gain (clean) channel and adjustable gain channel. The amp has a 12ax7 tube for it's pre-amp and this was the reason I choose it. It has headphone/line out and a socket for a cd player.

The amp is ok as a practise amp but has a few drawbacks. It has a large level of background hum, clean is a bit thin and reedy and will distort if fed from a HB. Using it with the gain control allows for a reasonable bluesy tone, but Im not too impressed if you turn the gain past about 12 oclock, seems harsh.
Might benefit from a better speaker, running into a 12" fender unit improved matters, but it was way to quiet because of impedance mismatch.

No probs yet.

If it failed I'd either fix it myself or use the rather nice case to build a low power valve amp in.

I've only been playing about 6 months and this amp was bought because I had a limited budget and it seemed to fit my needs the best. Blues was the way I wanted to go.
If lost I wouldn't replace it.
What I love, it's small and easily carried, really looks the part and is nicely finished. Can do a reasonable blues tone, but only over a narrow range of settings.
What I hate, that go***mn hum.

This is a follow up review ... 1 1/2 years later.

Noisy - An electrical hiss would show up on intermittently after the first 3 months. It is now a constant buzz.

Noisy over time.

I suppose I could have contacted the company for warranty work but shipping would cost $20 for a $59 amp ..... why bother.

This amp is still a great value. You still can't beat the price but, in some respects, it isn't a free lunch. My overall score is from 10 to a 7.

PS. I still use the amp several times per week. I see no reason to get another practice amp.

2006 model assembled in China. Features are what you would expect in a low priced tube preamp unit. Has clean and distortion channels not foot switchable. Great practice amp I use with an AX3G box to play any style music. Not many features a basic practice amp.
It does have a CD imput and headphone jack, also gain and shift buttons.

Good sound but may change the speaker for full blast capability. Don't use the distortion channel it is ok though, I use it with a multi effects box with n/r for a mind blowing sound. It is not noisy but naturally that depends on your pick ups and direction.

Had it about 6 months no problem.

Never dealt with them.

I have been playing for 23 years. I play a Casino, MIA Strat, MIM Tele, Epi Les Paul Classic Plus and a Guild accoustic thru it and they all sound great. For the money you can't beat it. For this price, around 60. U.S. dollars, It would be a sin to complian about more features. If it would have a flaw I would say it is the speaker, but that is a minor easy fix. Also the distortion is just ok, nothing great but again for the price it's a bargain.

This is the Behringer Ultracoustic AT108 Acoustic Combo Amp. 2005, I believe. Somewhat versatile, 2 channel -one mic, one guitar. No channel switching, effects loops, ext. speaker, etc. There is a CD input and a headphone out. It was only $59 new.. but I still wish it had a couple things like an effects insert jack for the mic and guitar or, even better, a separate insert for mic and guitar. Reverb would have brought up the price.. but without an insert jack, you can't add external effects on the mic/vocal. I'll probably open her up and see if there's a way to tap the headphone jack to use as an insert. Plus an external speaker jack would be sweet. It's solid state with some sort of "virtual tube" technology... whatever, it's not as harsh as other clean SS amps I've used. Standard 3 band EQ -I'd love a sweepable mid, but..again for the money. Most importantly it is tiny and lightweight: 14-1/4"W x 13-1/4"H x 6-1/2"D at 12 lbs. Feels like 5 lbs. I can easily give it high marks for what it is- an inexpensive, small, lightweight acoustic amp for small venues or home use. Great for open mics ! Maybe I'll try an external speaker cab by easily tapping the mic connectors.

Tried it with an Epiphone Masterbilt with LR Baggs Element and a Seagull Cameo with the Quantum piezo/mic combo system. The Seagull had a rounder sound. This little amp has a lot more volume than the speaker can handle. A tad too much bass or lower mid and the little speaker will start to distort. It really needs a $50-100 speaker replacement -maybe a Jensen Neodymium or something with some more muscle that can put out bass frequencies -and combine that with a piezo horn. But, again, they couldn't do that for $59, so for the money, it is very reasonable. I tried out a new Behringer V-Tone Acoustic pedal that I bought with the amp and that gave me much greater tonal flexibility. What is really nice is how small and light this puppy is and yet it will still pump out enuf sound for a small coffee shop gig. Not the holy grail but, for the money, I doubt there's anything currently out there that's close.

Haven't had it long enuf. My other Behringer gear is still running strong, so I'm not worried.

Well.. I've been waiting for a reply for a couple of weeks for my question regarding tapping the headphone as an insert. It's the kind of question that never gets sent to the proper techy, so I wasn't expecting much.

I've been playing for a couple of hundred years easily. I've been a very selective gear junkie over the years and I believe I'm satisfied with this purchase. I may try another speaker, add an external speaker jack, try to put in an insert -then this would be one extremely sweet little amp. 'Course that'll have brought the price up to well over a $100, so considering what your getting for $59 (OK, just call it $60) you shouldn't be disappointed. I recommend it if you are like me- probably have other nicer heavier amps you could use but want something you can bring to the coffee shop or small jam in one trip from the front seat -including the guitar and cord/effects bag. Just don't expect the existing speaker to handle the amps potential in the bass department -just won't cut it. Otherwise, sweet!

This hybrid amp features a tube preamp united with a 15 watt solid state power amp. A generic 8 inch speaker with a 20 watt rating is enclosed in the black tolex covered MDF cabinet. Controls are gain, bass, treble, and master volume. Also incorporated is a CD player input and headphone jack.
I bought this amp because I needed an "amp fix" and was sort of interested in a small practice amp that weighed less than my VOX or Epiphone amps. I play in a jazz/soul/funk band and I needed something small, light, and tonefull. This amp fits the bill and is plenty loud if your bandmates use dynamics.

I play an Ibenez Artstar hollowbody with humbuckers. I also play an early 80's G&L Strat with selectable pickups. My playing style is more BB King and Marc Knopfler than "shredder." This amp works well with this style and if heavy distortion is your thing, it will get very nasty....but in a solid state kind of way more than class A.
Don't get me wrong, the thing is "tubish", with an emphasis on "ish."
The controls do offer a lot of variety. With the "Gain" button unlatched you have a ultra clean solid state sound. At max volume the speaker will break up and rather unpleasantly. With the "Gain" engaged, you get bluesy tone at really low settings. Bringing up the gain you start getting a bit more Angus. Crank the gain and the distortion is pure Tony Iommi.
The amp at idle is fairly quiet and remains so for the most part.
I have some mod suggestions in the reliability section.

Built very well...finish work is excellent. I took the chassis apart and examined the electronics. PC board looked like automated work, but very clean and worthy. The 12AX7 tube is ceramic socket mounted with a spring hood retainer. The power amp is a single pentawatt chip mounted to a heat sink. Now....let's talk mods:
I believe this amp would perform better with a lower gain preamp tube. Another person suggested a 12AU7 but I think that's too low. I recommend the 5751 which has the same grid and plate voltage of the 12AX7 (no rebiasing) but has a voltage swing of 70 (the 12AX7 is 100..the 12AU7 is around 40). I believe this mod will lessen the "harshness" of the pre section and tame the distortion ratio significantly without jeopardizing the overall volume. The only problem will be getting the stock tube out. Not much room so be patient and carefull. Also take the time to place molex connectors on the speaker for easy off and on. BE WARNED, THIS WILL VOID YOUR WARRANTY...AND BE SURE TO UNPLUG THE AMP BEFORE TAKING IT APART. KEEP TOOLS AND FINGERS AWAY FROM CAPICITORS...THEY WILL RETAIN A CHARGE THAT IN SOME CASES CAN BE DEADLY.

Just got it. I have other Behringer gear...built well but there are lemons with anything.

I have been playing for twenty years and owned a lot of gear. This amp is so inexpensive that every young aspiring guitarist should own one. If you are buying an amp for a new player it is ideal because of low cost and decent tone. If you are a tone-minded player you will admire this amp for what it is. Perfect for living room jams and would be fine in a small club with volume restrained players. Mic it up and you could do any size gig. If you really want sweet tone and a cheap price buy an Epiphone Valve Jr. for $120. This Behringer is for different use and will be nice for casual playing. Can't beat the price and workmanship!

Jan2005 I believe this came out and that is when I purchased this amp.

Clean is clean, and Gain is gain and these two sounds are switched using a switch on top. It is best regarded as a single channel amp however that would only be the case if it had no switch.

It has a 12ax7 valve which is used for preamp distorsion. This was the main reason for buying this amp to get the blues cleanish/dirtyish intermediate area that is valve territory in a quiet practice platform. Yes I have a Marshall Head but that's no good late at night etc.

I put 6 for features empirically, however it's a 10 cause it has all I need.

I have changed the stock speaker about week 2 for a Jensen C8R. The stock speaker is almost atrocious (not unusual in a practice amp and nothing to be disappointed about). I felt that the amp was actually good enough to warrant a speaker change and tried it out on an educated gamble. It improved things 200% imediately noticable some strong clear bass with full mids and clear highs. Woohoo, Houston we have definition!! ;)

I also took out the chassis and ran a bead of black silicon along the controls area front lip where it meets the cabinet. This is because with the speaker change the fuller bass response occasionally made the chassis vibrate against the cabinet at higher volumes which sucked. Now it is good and has not had troubles.

I don't run the amp that loud, and it actually isn't that loud when you do. It is great sounding and respondes well to pick pressure so it is of benefit to practice through this amp.

Main axe is a Gibson Les Paul Junior Special Plus. It has humbuckers of type 490R/498T for the Gibophiles - I use the middle position, ie. nasally two humbucker twang.

Gives a great rendition of good midrange honk. Tone is clear and singing for blues this way.

Honk settings (lol)
gain:, [bass] and [treble] all at about 10-11 o'clock.

Gives tweedish grit clean when played soft and thicker overdrive tones when digging in.

As I said purchased Jan 05 and it is now August so 8 months of moderate use with no trouble. My one, and I suspect all of them makes a loud pop when turning on (I guess that's the solid state bit).

playing a while sine 1985-2005 so have had some gear in that time. This is THE BEST by 100X (well at least 3-5X) practice amp over other practice amps I have had.

I love it's size, it's looks are nice to, the finish is OUTSTANDING. I was shocked at how much amp and nice cabinet bits you get for the money. Even the manuals are generous stuff.

I would recommend this unit stock (don't mind my speaker changing) as a very good amp for a guitarist to use at home. With speaker change I have actually dragged it out to a small gig and it filled the room stand alone well enough, with a small PA for vocals.

Personally IMHO - stock speaker is a shocker, with Jensen C8R this amp is very impressive and offers low cost, low maintainance great practice tone.

I am still considering a little Fender Champ or a Gibson Skylark (similar) which a little 5 watt tube amps -- for practice however for the money this little Behringer really is a class act and the only clear choice BY FAR in the practice amp arena.

Rock on!

Has very usable tone controls, gain, CD input, headphone jack, control button for mids, lightweight 15W 8" with a tube preamp.

For the price paid and the fact that it is a practice amp ... I should give it a 10.

1970's made in Japan Telecaster - all stock. I play blues and blues based rock from 1960's through 70's. This is a practice amp so all comparisons/opinions start from that point. You look at other small practice combos below $75 and this thing sounds the best - period.

The preamp tube definitely colors the sound. Play with the gain, volume and tone controls to find the sweet spot. This thing blows away anything with an 8" speaker that I have ever tried.

My favorite thing to do is jam with people with thousands of dollars worth of gear. I walk in with $165 worth of gear and watch the looks on their faces when they hear me open up.

Hasn't broken down in the month or two I've owned it. Time will tell....

I'll submit another post if it breaks down.

Don't know. Warranty is something like one year, 90 days for speaker, 30 days for tube if memory serves.

For $60, I'd probably just buy another one if I damaged it.

I've owned several practice amps (and tried many others)in the last 30 years of playing. I don't expect much in terms of quality sound and I'm still often disappointed. Crate might as well stop making practice amps because these things will sell like crazy. $60!!!!

This amp is different. The quality of sound, the features and the price are really unbelievable. But it is really great for jams with buddies or living room rockin'. I would still like a half watt boutique amp but now I'm in no hurry to get one. I may use that $500 I saved to get lessons, go to concerts or buy other guitar gear. As far as practice amps go, I'm very satisfied!

'05
China
Great Champ style howler, only louder.
Good Blues tone, plus it has some clean headroom on the clean channel if you turn the bass down.
I use it for Jazz with an archtop in intimate settings.
No reverb or footswitch jack, but it does have a headphone jack.
The speaker sounds good and can take quite a bit of volume. It says 20 watts on the speaker. The amp is 15 watts.

It hums a little.
Has a channel switch kinda like a Fender, and a fat switch too, like a Fender.
It switches between the tube (12AX7) and the clean channel, which doesn't seem to use the tube. Has a Gain knob and a Master Vol, as well as a bass and a treble tone pot.
The jacks are steel.
It gets pretty distorted, but the speaker is probably the weak link. It don't take too much bass, so it can get kinda buzzy if you're really trying to get mondo distortion, but the louder you turn it up the better, you have to turn down the bass at some point though, or the speaker starts hitting the stops and sounds rude and flabby.

One month so far. No problems.

No experience

20 years.
I have other amps, but this one is handy small, like a lunchbox.
Sometimes I use a processor to get reverb.

I love it: it's small, sounds great, and is loud enough for jams. If it were mic'd it wouldn't have any limits. Use a processor and get every sound there is.

'05 Made in China, designed in Germany, 15 watt "practise" guitar amp.
1 preamp 12AX7 tube.
4-ohm 8" Behringer speaker.
A real metal 1/4" inputs and phone jack and lock nuts on steel chassis (yay)!
No reverb.
Minimalistic approach with good tone and volume for the type.

Using a stock (single coil pickups) Fender AV '52 RI Telecaster I love the sound it gets from quiet turned down (but not thin sounding), to loud enough and good sounding enough for live performance.
The character of the Telecaster cuts through very well and there's a good tone range available by switching modes and adjusting the knobs.
Gets a big hollow sound on the neck pickup, and the crisp bridge pickup can be controlled without losing its liveliness.
Great for Blues at small club levels with just enough "grit" for nice feel and emotional expression.
The speaker can be a bit farty if you get loud with the bass rolled up too far, but that doesn't mean you have to roll off all the "guts." I just turn the bass down until the speaker can deal with it, and it sounds pretty full range still.

I cut the speaker wires and hooked it up to one of my sons friend's Marshall 4 X 12 cabinets in 4 ohm setting and it was quite a bit louder and fuller.
It would not be a waste to run a 4 X 12 cab with this amp. It's quite viable as a guitar amp you could gig a medium size club with when used this way, but that won't make it sound like a Marshall or Metal rig. But it was eye opening.
15 watts pushing a lot of speakers can be very loud and usable far above "practise amp" class.
Overall I really like the sound and output level of this lil' ol' amp.
It makes me wonder why boutique amps are all the rage when you could buy one of these once a year (the warranty length) for twenty years and be money ahead.
Sounds like premium components to me

1 year warranty.

I've been thrashing it for 5 or 6 weeks with no troubles.

The speaker seems to take it pretty well without any trouble signs.

No experience

Started playing guitar in 1960.
I've had about everything through many eras, but prefer Telecasters through small "tweed" sounding type amps.
Fender Champs don't have enough volume for me, and these sound good to me (I have bought a second, and sold my 60 watt combo amp, as it just sat in the car as a spare since I like this/these so much).

This is actually a viable amp for performance, given that a Tele can "cut through" while the guy with a HR Deville needs more power for his "thick" sound.
In a band, this does OK as long as the volume wars don't blow the room out.
I bought the second just in case I need more power someday, as I've been at the limit with this (but got through).

Bought this amp new in Feb. 2004. Single channel, 15W practice amp with 12AX7 preamp tube, 8" speaker, open back cabinet. Very simple controls: master vol, gain control, bass and treble knobs. There is a shift button (on/off) which effects the mid-range freq. and a gain button (on/off) which enables the gain control. Headphone out and CD input are also included. Great vintage look with chicken head pointer knobs and white piping around the speaker cloth.

I use it in the classroom with a 5th grade jazz/rock combo. Plenty loud in this venue.

The "hand selected 12AX7 vacuum tube" used in all the marketing for this amp is over-rated IMHO. It's only in the pre-amp section and most of what you hear in the output section, or power-amp section is solid state. It still has some good features for the price.

When I plugged in this amp out of the box, it was noisy. Lots of hiss. Annoying not vintage, at any volume. I solved this problem by swapping out a new tube which I'll explain below...

I use this amp with a Mexican made Strat and a Squier Custom Tele with a single coil neck p/u and a humbucker at the bridge. I am impressed with the variety of sounds you can dial in with this amp. When the gain button is off, the gain control is disabled and you have a nice clean sound that is plenty loud with the master volume turned up all the way. The shift button seems to boost/cut the mids in this configuration. Bass and treble do a decent job.

With the gain button on and the gain control enabled, you have your typical solid state distortion that can get pretty ugly past 5'oclock. With a lower gain tube, I think the distortion is manageable and works well for blues or classic rock. The shift button and bass/treble knobs give you several eq options again in this configuration. I have not used the headphone jack or CD input.

Too soon to tell. It's built well and I would not be worried if it were dropped, which is a concern for me since I work with kids who tend to be clumsy with equipment.

I had been doing some mods on another tube amp I own, and decided to contact Behringer about swapping in another tube. They politly informed me that this was to only be done by a qualified service tech blah, blah, blah voided warranty etc. With screwdriver in hand, I swapped the "hand selected" 12AX7 with a "hand selected" (meaning, I used my hand to take it off the shelf at my local music store...) 12AU7 tube. This lower gain tube solved the annoying noise problem and made the gain control much more manageable.

*Email me if you want more details on how to do this. Warning: it will void your warranty with Behringer.

If you know something about electronics, you might be able to reduce the initial hum by twisting wires and all the other simple tricks I've only heard about and never tried.

I have been playing guitar for about 3 years. Teaching music for over 20 years. I own several other practice amps and modelers: roland microcube; behringer vamp 2 and korg ampworks. My Crate VC508, a 5 watt, single 12AX7 preamp tube and a single EL84 power tube amp combo with an 8' speaker, when played side by side with the AC108, the Crate sounds louder and fuller- but for the price, I think the behringer is a good deal, if you can reduce the noise factor.

I like the simplicity of the controls. As a first amp for a new guitarist, it's a winner. I plan to use it as a teaching tool so my student guitar players who use it have to learn how to actually dial in a sound rather than choose a preset.

It's a new amp from Behringer (january 2005). It's a 15 W combo amp, in a 8" speaker. Very simple, but designed with a 12AX7 tube as preamp. The tube can't be seen from the outside, but is really present inside (I checked ;-)
Very nice vintage look. Doesn't look as cheap as it is...

Gain, gain switch, Bass and treble knobs, Eq with a "shift" switch to choose between a guitar amp sound, or a flat sound, from what I understood. Anyway this switch is useful to change sound...

There is also a CD input and a headphones output. Missing an output to record, after the tube preamp.

Wow ! I don't know if it's intended as only a practice amp, it is not very loud, but has really an honest sound, can be clean or the "gain" can adjust tube distorsion. Very effective. I like it very much near my rack of old Harmony guitars.
I never tried other so small amps, so it's difficult to rate it.

I read dreadful stories about behringer gear. I have many of their stuff and never had a problem with it (sound processors, v-amp, and another very nice amp, the gm110, Trademark 21 clone).
This amp is new and I still have no experience with it, but my other Behringer amp works every day and never failed.

I am sure you can't find a nicer amp for the price. Excellent companion for the bedroom, travelling or practice. I suppose it could be a nice harp amp too.
