    15-Watt, 1x12 Guitar Combo Tube Amplifier with Celestion Speaker & Spring Reverb

    Get superior guitar tone and flexibility using this 15-Watt, 1x12 Guitar Combo Tube Amplifier with Celestion Speaker & Spring Reverb from Monoprice!

    As the title indicates, this guitar amplifier features a 15-watt tube power amplifier and a Celestion brand speaker. It uses three ECC83/12AX7 preamplification tubes and two EL84 power tubes for the amplifier section, plus a Celestion Red Truvox 1215 speaker. The EL84 tube is the tube that powered the Mullard amplifiers favored by the British Invasion bands of the 1960s. It can produce a full output from a relatively small signal and is therefore easily overdriven to produce that distinctive chiming, treble-heavy sound, especially when compared to the 6L6 tubes more commonly used in 1960s era American guitar amps.

    The amplifier handles frequencies between 80Hz and 10kHz, with hum and noise -75dB below the rated power and 0.5% total harmonic distortion. It includes a Low input and a High input, with the former attenuating the signal by approximately 50% and the latter being easier to overdrive. The cabinet is ported in the rear and features a leather handle, cloth speaker grill, and a cream-colored, textured, synthetic leather exterior with chrome corner guards.

    The amp features a genuine spring reverb with the ability to enable it remotely using a foot switch. It supports FX send and receive, so you can either connect it to an effects processor or use the send/receive connections as line out and line in connections. Two inputs allow you to select between the full power mode and a 1 watt limited amplification mode for recording or late night practice sessions.

    Great bang for the buck
    I'm impressed, great quality and tone for the price. I bought it during a Monoprice sale, great deal with 20% off.

    I love that it has gain + master volume, and an effects loop. I'm guessing the "Tone" control is really a "Presence" control. I wonder if the schematic for this amp can be found somewhere, I wonder what circuit design this amp has modeled.

    I've got a number of tube amps (Marshall JCM800, vintage Fender Champ and Bronco, Crate VC). This is a perfect mid-sized amp for small rooms, with a great wide range of tones. The EL84 pairing has an expected chimey brightness. In terms of power, do you really need more than 15W? Probably not...and I love that about this amp. If you're playing small clubs you're probably gonna mic the amp anyway.

    The build quality was really nice. Cream tolex was perfect, no scratches/glue/peeling. Knobs turn smoothly. Some of the screws (which are recessed by washers) stick up a little high, but that's pretty minor.

    I wish the reverb was a longer spring reverb it's really short and "boingy". It's also extremely sensitive to the amplifier being touched/moved. Wish it had a standby switch too. All that said, for around $200 you have a really great sounding portable little amp.

    PROS: Value, tone, master volume, build quality

    CONS: Boingy short reverb, no standby switch, no detachable power cord.

    Great tone
    The reverb is fine at 2 or 3 or less. Sometimes there's a small background noise that I haven't heard in other amps but I haven't ruled out the cause. Fantastic tone for this price. Lightweight, EL34's provide a great tone. Input jack has been a little finicky.

    PROS: Great tone, great price

    Nice Amp - Great customer service for Monprice
    Very nice amp - can't beat it for the money. Reverb is the only weak spot, but that can be easily upgraded for a few dollars if desired. Also - I received great follow-up customer service from Monoprice.

    PROS: Great sounding small tube amp and very reasonably priced! Built like a tank.

    CONS: The only weak link is the reverb. It's still useable, just not he best.

    Great Amp
    this amp sounds great. i plugged in the monoprice tele and the tone was butter. this amp sounds way better than any of the $200 'trans-tube' or 'transistor' 'modelling' amps that are out there. this monoprice amp might even sound better than some of the marshall amps.

    PROS: great tone. simple controls. very straightforward. 12" speaker. tubes.

    CONS: haven't had any yet

    Great Classic Rock Tones
    I've been plying guitar for about 30 years. This is my first ALL tube amp. I've had several tube pre-amps and modeling amps with dozens of effects but I'm pleasantly surprised by this bare bones combo. I have no issues with the reverb (but would prefer a longer decay time). I did notice that the tiny reverb tank is mounted on a vibration isolating foam pad. I'm not sure if this pad is present on the units where people have mentioned issues with the reverb. The variety of tones available is quite good. With the gain boosted I'm able to effortlessly get a nice feedback going when I want that hard rock Hendrix vibe. Pinch harmonics also chime out with ease. Playing ZZ Top or Zack Wylde has never been so easy and this is without an overdrive pedal. As others have mentioned the 1 W setting seems more like 5 W but this isn't an issue. The 15 W input gets loud enough to scare my wife and daughter out of the house. At this point I'm enjoying the amp "as-is" and haven't tried any effects pedals or used the effects loop. A head only version of this amp would be a perfect addition to the Monoprice line-up. I've been wanting an all tube amp for years but could never justify the purchase. I saw the price, took a gamble and couldn't be happier. Look for a coupon and free shipping and take the plunge. You won't be sorry.

    PROS: Great price. Fun to play through. Classic "guitar here" rock tones with just an amp, guitar and cable. VH, Zep, Jimi .... it's all there.

    CONS: No cons at this price but a tweed version or head only version would both be killer.

    I've Always Wanted One! Dream Come True.
    I Did Not Know What To Expect, I've Never Had A Guitar Tube Amp Before Now. I Knew They Sound Better Than Solid State Guitar Amp's, I Had No Idea The Awesome Far Out Sounds That Can Be Made With A Guitar Tube Amp Until Now. This Thing Is Built Well & With Tweaking The Knobs I Created Some Far Out Sounds With My Guitar & Cable Going In, I'm Talking Raise The Hair On Back Of My Neck Far Out Sounds. Tweaked To Make This Sound Like A Magnetic Audio Tape Burning Out Like An Old Muscle Car With A Ghost Vibe, Used The Tremolo On Guitar It Was Spooky. I Think You Should Buy This Thing If You Want A Guitar Tube Amp!

    PROS: It's A Guitar Tube Amp, You'll Understand Why This Is A Pro Once You Play Around With It.

    Well Built Considering The Low Price, Very Surprised.

    Just Can't Beat That Tube Sound, I like Messing About On Electric Guitar Now.

    CONS: I Worry About Breaking it! Because It's So Nice!

    A Great buy!
    I read the reviews, I patiently waited for a deal, and I made my move. Only have it for a few days but my initial assessment is this is a winner and a must buy. Unlike other's I have found the reverb to be quite acceptable. The controls are VERY responsive. It handles pedals like a champ. If it gets better as it breaks in this will be a phenomenal deal.

    PROS: sound, power, features

    CONS: None

    This is a great sounding amp!
    I was fortunate enough to be at the NAMM show and my friend and I were walking by the Monoprice booth. He mentioned that this little 15 watt tube amp had gotten good reviews so I walked over and asked if I could plug in. The guys at the booth were super cool and got me hooked up right away. I was immediately surprised at how good the amp sounded and felt to play through. I am a bit of a "gear snob" so I was fully prepared to hate this amp! Before you knew it, we had a little jam sesh going and I was really digging the sound. This was straight into the amp with no pedals. When I asked what the price was, I couldn't believe that an all tube amp that sounded this good could be so inexpensive. I ordered one just a few days later (I saved even more money by waiting for a sale) and when I got it, it was exactly as I remembered from the NAMM show, except now that I had it in a quitter environment without all the background noise it sounded even better! I couldn't recommend this amp more! It's a very loud and clean 15 watts, totally gigable. Even more surprising, the built-in overdrive sound is really nice too!

    PROS: Light weight, inexpensive, all tube, sounds amazing, built-in effects loop, powerful enough for club gigs.

    CONS: The only slight negative would be the tiny built- in reverb, which sounds okay but not great. It doesn't matter to me because I use an awesome sounding reverb pedal anyway.

    Love this amp
    I prefer this amp to my Blackstar HT40 and Mesa Dual Rectifier Roadster. The controls are simple and I can change the tone with pedals rather than fiddling with multiple amplifier controls. I know it's good to warm up with a standby switch (which this one doesn't have) but the single switch involves less forethought. Great sound, only slight background noise when the guitar is not playing.

    PROS: Great sound
    Light weight
    Effects loop

    CONS: Mediocre reverb
    Jack for footswitch but none available
    One knob was missing. Monoprice originally wanted me to return and reorder but I'll use a non-matching knob I have on hand if they can't find a knob. Hate to have them incur 2 way shipping for a tiny knob.

    Plays above it's price point!
    My wife has enjoyed her 5W Monoprice tube amp since it arrived the first of the year. I shocked her with the 15W version a week or two back. She was initially upset, saying we didn't need it and couldn't afford it. She returned to my office after 30 minutes of playing and proclaimed, "Never mind... I love it... it's mine and it stays!". The 5W job will go with her for her lessons, as her instructor's new big Marshall tube amp had to go back for service! Yes, the spring reverb is a joke - I'll replace it! You can get audiophile quality - or tube-type distortion - and it has a 3 channel EQ and tone control. Her Fender Amer Std Strat never sounded better - same for her Gibson LP and her weird Hofner violin-shaped 6 string, too.

    PROS: Plays well above it's price point!
    Like the 5W version, it worked right out of the box.
    The Celestion 12" speaker broke-in within 10-15 hr of playing and, like the 5W-er's 8" Celestion, sounds fine!

    CONS: Shipping wasn't included - but I knew that!
    A knob had fallen off (Now I'm nitpicking!)
