    5-Watt Guitar Amplifier, Portable Recorder, and USB Audio Interface

    You will always be ready for a performance or recording when you have this 5-watt Guitar Amplifier, Portable Recorder, and USB Audio Interface from Monoprice!

    This little 5-watt amp delivers a big sound with plenty of loudness and clarity for ad hoc outdoor performances. It has a built-in guitar distortion effect, so you can get great sound without needing external processors. In addition to the 1/4" guitar cable input, it features a 3.5mm microphone input, so you can add vocals to your performance.

    A 3.5mm auxiliary input allows you to connect a smartphone or music player. The music will then play through the amp with your guitar and/or vocals in the mix. If you don't want to carry around an extra device, just plug your microSD card into the amp and play your music directly. It supports playback of mp3, wav, and wma audio files.

    The microSD card is also used for audio recordings. You can record your guitar performance, along with any mic or aux inputs, to 128 Kbps mp3 files on the microSD card.

    An added feature is the ability to plug the amplifier into a PC or Mac using the included mini USB cable. The amplifier is true plug 'n play, so no drivers disks are needed. Your PC or Mac will automatically install the drivers it needs for a USB speaker system.

    The amplifier is powered by an internal 1500mAh battery.

    Will this work as an interface with my computer? Can I use the USB connection to feed sound in to the computer and record on my computer?
    Antonio Z on Sep 6, 2017
    BEST ANSWER: I've used this asa recorder for guitar and then sent the signal via usb to the computer (via garageband and audacity) as for the unit serving as a "stand alone" interface, it DOES work, but i wouldn't rely on it for anything more than maybe 4 tracks. if you know what you're doing when it comes to digital recording, then you can play around with it and get the best results you're looking for. I hope this was helpful. -Mike

    2 months in China
    I've had my little unit as a practice unit in my office for almost 2 years. I'm now on a 2 month teaching gig in China and this is paired with my travel guitar. It is tiny, powerful enough to practice and the battery life is amazing. I use it in hotel rooms, trains, the park, and it has withstood the rigors of travel including bouncing around in a gig bag and excessive moisture. It's a great little unit!

    PROS: Very durable.

    Easy to use.

    Great rechargeable battery life!

    Despite other reviews it is rather clean when dialed in properly.

    CONS: It does not attract hot women or peel paint off of hotel walls.

    Exceeded expectations
    After seeing one of the reviews saying that it sounded like playing through a transistor radio, I was a little hesitant. I keep my MIM strat in my office at work so that I can squeeze in a bit of occasional practice, so I wanted something small, headphone friendly, and able to plug an MP3 player into for backing tracks. I have to say I am really pleasantly surprised with this little thing. It uses a micro SD card to store MP3's, or you can plug in a player as an aux input, and the guitar and MP3 volume have independent controls. The distortion setting is all-or-nothing, but using the clean setting with the volume cranked up on the guitar produces some drive.

    The speaker is dinky but sounds better than I expected, and it's not bad through headphones, which is what I typically use since I have this at work. It also has 4 different equalizer settings to shift around the base, treble, and mid-range. Experimenting with the different settings can really improve the sound quite a bit, particularly when boosting the base, which the speaker seems to handle better than expected.

    Here are a few other observations:

    1. You can only mix the guitar input with the auxiliary input when recording, and not with music stored on the SD card. In other words, you can play along with MP3, WAVs, or WMAs on the SD card, but you can't record with them (probably because it can't read and write to the SD simultaneously), but you can record together with an MP3 player plugged into the AUX jack and/or a microphone plugged into the MIC jack.

    2. The guitar recording is really not bad at all. It is certainly not production-quality, but for tracking my own progress or to share informally I think it's usable.

    3. When recording the guitar input together MP3s played from my Android phone using the AUX input, I had a hard time getting enough volume out of the MP3, although the guitar sounded pretty good. It may work better with other devices, but the best recording approach is probably to record the guitar alone, and then mix in the jam track on a computer.

    The USB interface supports charging the amp's internal battery and using the amp as an external powered speaker for the computer. Although it's not mentioned in the manual (which is well-written in grammatically correct English), when it is plugged into the PC you can also access the SD memory via the USB for immediate access to the recordings, or to copy backing tracks to it.

    On the back it has a belt clip, that detaches and can be inserted into the lower part of the amp, turning it into a tilt stand (and making it much easier to use).

    I pretty much got it so I could practice with headphones and backing tracks, but it is definitely workable for quick recording and overall I am fairly happy with it. As one of the reviewers posted, it is probably great to bring along when checking out a guitar when an amp isn't available, for travel, or as a headphone amp.

    PROS: Great set of features: SD card MP3 storage, recording, equalizer, several tone possibilities, USB access

    CONS: A little light and unstable when propped up on it's stand, sound is a little bit tinny, recording single source is good, but quality drops when recording guitar together with backing track.

    hours of research led me here.
    I was looking at those little cig pack amp affairs when I found this little hidden gem. Mine works flawlessly but when stuff comes with the stamp "Made in China" there's bound to be a lemon or two. Monorpice has fantastic customer service and they want you as a lifetime customer.

    PROS: All of the love from this review is based on the price point. Cables click in solid and buttons have a solid click to them. Users manual is adequate at best but I think it's very easy to figure out. 4th button from left is marked M for mode. Scroll thru modes from there. I have been able to play MP3s on a microSD card, record my guitar and upload it to the Mac with NO PROBLEM. As for the battery life, I could not be more satisfied. Do NOT step on this product with a hobnailed boot.

    CONS: Wait until it goes on sale for $19.99. The waiting is the hardest part. I think Tom Petty said that but probably not about the Monoprice 611700. Still, at 25 bones it's a keeper. Monoprice RULES!

    Excellent, perfect!
    First off, if your looking for great quality sound out of this little speaker than look for something else, although you probably wont find anything that sounds great in a small size anyway nor less than the price of a Lamborghini!, but for $20 this lil guy does exactly what it's intended to do and does it great!
    It sounds good through headphones and also works fine if I patch it through my small practice amp or home stereo.
    I can record my daily practice sessions and song ideas and than playback and listen to it all and work on any mistakes or needed changes, I can also swap my ideas to my laptop and edit the files and work on entire songs, this lil guy is VERY versatile! It has been PERFECT in every way for me since it arrived last week! Like one reviewer stated it would have been nice to have a file delete option on this unit itself but, it's really no big deal that it doesn't, I wasn't looking for 296 track recording studio quality but when I play back files they sound excellent enough! In my opinion this was really well worth getting and so glad I did! It also being rechargeable that will save me a fortune on batteries! It really is a great deal and so convenient!
    Thanks Monoprice! You guy's always Rock! \m/

    PROS: Convenient, practical, easy to use, records/plays back, totally portable, excellent

    CONS: None really

    5-Watt Guitar Amplifier

    PROS: This is my second purchase of this product. My son-in-law borrowed my first one, and I haven't seen it since. For the size, and what is intended to be the product should be a Consumer's Digest "Best buy". The quality is above average, the user-options are great, and for what it is - the sound is good. An ideal product for at-home practicing.

    CONS: None that I can think of.

    Very handy
    I like the ease of use and portable nature of the amp. Great for a quick practice or on the go.

    PROS: Small, easy to use and sound is pretty good for a small portable amp. Great for quick practice or travel.

    CONS: No real cons.

    Pretty Good Pratice Amp
    Thanks Monoprice, this is the perfect little practice amplifier for a beginning guitar player like myself. It's loud enough to hear, the sound quality is pretty good, it's easy to use, and it's small enough to move from one room to the next (or to being somewhere). The MP3 playback feature is just icing on the cake.

    PROS: Small, easy to use, MP3 playback, nice "fuzz" sound, plenty loud.

    CONS: A little "cheap" feeling, hard to get a "clean" sound out of it.
    January 18, 2014
    OK Kinda
    Basically it's like playing a guitar through a transistor radio ... OK, sound sucks, but I'll use it when I want to check out a guitar I'm buying on Craigslist ... sounds is poor but I can make sure pickups work, pots are not noisy, etc.

    PROS: Does some amazing things ...

    CONS: Sounds is really poor

    I bought this amp to make my cell phone louder when outdoors. It does so nicely with a cord attached. Trying the other features is what eats up your time.

    I have stopped trying to get it to be a USB extension speaker on a Mac Mini. I then tried it on a PC laptop. It was dead again also.

    The indication is correct while charging but it never indicates when it has completed. I charged it three days and gave up. I assumed both charging indicators would display when unplugged from the usb cord. The top LED goes dark and the bottom one remains lit. I assumed it was only half charged.

    I discovered lastly it had an SD card slot. Cool! I loaded some songs, medleys and announcements on it. Very Cool! It completely eliminates having to amplify my cell phone and operating / holding two devices at once. In actual use, however, you have no idea how to get to the announcement amidst songs and medleys. You have to "channel surf" until it is located. Conversely, if you want to listen to music, an announcement is going to play eventually. I'll have to carry 3 different SD cards to overcome this limitation. When the last recording ends 5 WATTS OF UNRECORDED WHITE NOISE BLASTS before the amp makes the correction.

    You would think by now there would be several videos posted on different aspects of this amp.


    It does play an SD card

    It will amplify your cell phone w/3.5mm cord attached

    It did work for my intended purpose

    It may work as a parabolic mic headphone amp


    You have no idea what it is going to play on the microSD card

    Annoying 5W BLAST of white noise after the last song
