    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.

    Love this amp

    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.

    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.

    Great bang for the buck

    Pros: Value, tone, master volume, build quality

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

    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: Light, loud, great platform to work with.

    Cons: Reverb, speaker, and cheap tubes.

    I recently purchased one of these 15w amps and am extremely impressed. In my opinion it compares favorably to other similar amps that are much higher priced (vox ac15, fender blues junior). It is a well made small portable tube amp that could easily be used for gigging or practice. You will be hard pressed to find a better alternative in the under $400 dollar market that offers the versatility and tone of this amp. Now there are a few drawbacks to consider.
    1. Reverb. While I personally don't mind the stock reverb tank it can be underwhelming. It is fine if you use reverb as I do, which is to create a light ambient effect for your playing. If you need a lot of reverb or just a better option you will need to upgrade the tank or buy a pedal but there are plenty of options under $100.
    2. Tubes. The stock tubes do not sound bad, but they are made of very thin glass and i easily shattered one while doing a speaker swap. you can easily upgrade these to the tubes of your choice for around $50-$100.
    3. Speaker. The stock celestion 70/80 is not a bad speaker, but it is not a great one either. It lends itself well to a range of sounds which is what makes it popular, it also work well to give you an idea of what to improve. It tends to be very shrill in my opinion. Again there are plenty of options for under $100 that would be easy to swap in.

    So overall I am satisfied with my purchase especially given the price of admission. For another $200 you can easily make this thing into a reliable, portable tone monster.

    Pros: Looks Good
    Sounds Good

    Cons: Vacuum tubes might not survive shipping

    Amp was DOA with a cracked preamp tube, but has been performing admirably once it was replaced. If you don't mind the possibility of replacing a tube or dealing with MP's RMA process on the off chance you get a dud, order away! Fantastic little amp for the price.

    Small Dog but Big Bite!

    Pros: Small package Big Sound! Nice tube sound and tone. Visually pleasing.

    Cons: Not many cons. If I could change something it would be the reverb tank. Also remove the grate to be able to access the speaker area of the amp for storage.

    This amp is the perfect size for small to medium venues. As soon as I received it I put it to work for the whole week for a convention I had to play. This amp gives you the all tube sound on a budget. I get the reviews that down the reverb but for my style I don't use a lot of reverb. Plays nice with my Fender Strat as well as with the Gibson 335. So you get good sound from both single coils and humbuckers. It's lightweight so you can be mobile but don't be fooled this thing is loud even cranked halfway. I would definitely recommend this product. Keep them coming Monoprice. Perhaps you can offer this in a 100 watt head? LOL
