    Does it have built in microphone?
    A shopper on Mar 15, 2018
    BEST ANSWER: It does not have a built in microphone. It has a 1/4 inch jack for a guitar that would support a high impedance mic, I suspect, but I have not tried it that way yet.
    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?
    TAZMAN 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
    Does the USB recording now work on Windows 10?
    James M on Jul 9, 2018
    BEST ANSWER: I have not used the recording feature. According to the manual, when the amp is connected to the computer via USB, recording from amp to computer is not supported. You will need to record to micro SD card, then transfer the mp3 file(s) to the computer.
    Will not power on unless plugged into computer USB! Just received the 611700 today and it works fine as long as it is plugged into USB, otherwise no life. I have had it plugged in for a few hours, but still not life. Does it have to charge the batteries and for how long?
    R. Keith L on Feb 9, 2018
    BEST ANSWER: Sound like you may have a defective unit. . Please login to your Monoprice.com account. From there on the left hand side, under my account, you can go under request refund/replacement and from there you can process setting up and obtaining your replacement item. I hope this helps. Thank you!
    I want to use this with an acoustic-electric violin that has a passive piezo pick up. Does this support high impedance output from the violin pickup such as 1 Ohm?
    A shopper on Jan 24, 2018
    BEST ANSWER: the fast answer is this *should* work......

    the 1 ohm part of the question is nearly impossible to address.

    typically a low impedance pick up has at least 150 ohm.

    remember impedance involves more than just resistance.

    the great majority of instrument pick-up are in the 10-50 K ohm range
    Can you still use it to play while it's plugged in and charging?
    A shopper on Jun 2, 2018
    BEST ANSWER: yes you can. pretty cool little device for the price.
    Does this have built in microphone for recording?
    A shopper on Feb 19, 2018
    BEST ANSWER: It does not have a built in microphone. I bought a cheap lavilier microphone to plug onto the unit. So my daughter could play her guitar and sing. It allowed her to play through the amp and/or record what she was doing. It is a great unit.
    1) I can't get the usb speaker feature to work on windows 10. Any suggestions?
    2) is a micro sdHC card compatible or only just plain micro sd?
    A shopper on Dec 18, 2017
    BEST ANSWER: You may need to get an ASIO driver to work with the new OS. We are checking with our engineers for any updates.

    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

    Great little unit
    Great unit for the money. Bought two - one for a gift.. Works really well with or without headphones. Great for practice.

    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.
    June 9, 2015
    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.

    Love this multi use amplifier
    I love bicycling and instruments.

    Here's something musical and sound lovers on tour might use while traveling with their MP3 player listening to a audiobook, music, poetry, radio, PHONE -or- typing out their daily PC email cycling journal while listening to something pleasant -or- RECORDING narrated touring thoughts, sounds and acquaintances -or- playing a preferred musical INSTRUMENT or microphone amplified along the cycle trail road side, park or camp. It could be used on the premises of a B&B rooming house, continental hotel, motel, cafe or guest room and landscape. Its a small 9 ounce speaker with a built in 5 Watt amplifier and recorder powered by a internal rechargeable battery fitted inside a small box that is connected with a cable to a sound activating device or plug in a microSD memory card.

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


    Paid $37.37 for it including shipping. Has a 30 day money back offer but I'm satisfied.

    Arrived by USPS in three days (Fri-Mon) and has a nice clear sound from low to high range tones but no deep subwoofer response. I like it and it sounds much like my compared to 12" speaker amp but not as loud or heavy. While listening to it plugged into the PC it charged the battery at the same time. With the volume cranked up all the way its loud and distorts. After a couple weeks of use the distortion seems to be going away at maximum volume.

    Checked battery duration and the amps internal battery lasted 18 plus hours at room temperature listening to mp3 music files copied to my microSDHC memory card (can use up to 32 GB) from my PC computer. My old USB wall charger (not included) took 2 hours to charge the battery and the PC cable connection (included) less then 2 hours. While my USB wall charger was working I could listen to the mp3 files play or unplug the microSD card for quieter charging or check to see if the battery is fully charged.

    Wish I could shuffle the mp3 files and see what's playing for future reference.

    There's two heavy plastic loops on back for a strap (not included) to attach to the bicycle or person which I haven't figured out yet how I'll use it for myself. Love the plastic belt clip which converts to a stand for the speaker on my PC tray, chair or ground. For waterproofing I slip it into a one gallon zip lock plastic freezer bag.

    Didn't care much for the mini lapel microphones bought elsewhere all though they work close to one's lips. Still looking for a microphone to record water, storms, birds and other wildlife while bicycle touring.

    Well that's about it. I won't be returning this multi-use product because its well worth it to me to have while bicycle touring, around home and instrument playing wherever.

    PROS: Many uses

    CONS: Wish I could see which mp3 file was playing.

    great little amp!
    This little amp really does what it's supposed to. Unlike mini toy versions of full-sized amps, this thing dedicates most of its surface are to its speaker. Haven't recorded yet, but more than happy with the volume.

    PROS: Size, volume

    CONS: None

    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.
