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.

Works as advertised, merely adequate for electric bass

Pros: Versatile, okay sound for the size, 90's aesthetic

Cons: Bass response is weak, USB functionality largely useless

I took a gamble on this product because I wanted it for a practice amp for bass. Since it is intended for guitar, I wasn't sure how it would work with the lower register of the bass. Short version: it's okay, but far from great. Unsurprisingly, the built-in speaker struggles with the lower frequencies. Using headphones improved matters, but E-string notes on both my basses were still weak, and B-string notes on my 5-string were quite muddy. As other reviewers have noted, the distortion mode (which is on by default and must be switched off manually each time) basically raises the gain a couple notches to make the signal clip. Both of my basses are active, one is currently set to have quite a hot output and with that I was able to get it to distort reliably. The other bass does not have as hot an output (but is still plenty hot in other situations) and that one only clipped when I was playing hard, even with the volume pots turned all the way up.

All that being said, I can put the amp on my belt with a short instrument cable and headphones, and practice anywhere in (or out of) the house without bothering others or worrying about unfortunate incidents involving my instrument cable and a running 3-year-old. So despite the shortcomings in the low end, this was still money well spent.

I have briefly tested out the other functions aside from the microphone input and recording. It works as a PC speaker, but I'm not really sure what benefit that offers that you couldn't have by just using the audio cable. The aux input works fine if you want a little more sound from your phone or have a laptop with crappy speakers. That being said, for the same money, you can get a Bluetooth speaker with better (stereo) sound.

The MP3 player functionality is very basic and you don't want to load up too many songs, because you have to skip through songs sequentially until you find the one you want. As a practice aid, it probably has some use. Of course, if you want to pretend it's the 90's, just clip this sucker on your belt, strap on your Rollerblades, and listen to your tunes without worrying about the Walkman eating your tape.

Pros: This amp is portable and pretty easy to use, portable and low cost. Probably a good solution for practice sessions on an electric guitar.

Cons: The default mode seems to be "distortion". Turning that off (every time you turn on the unit) basically just turns down the gain on the amp, lowering the volume overall, and giving less distortion, but not really a "clean" sound. When using it to record, I can't seem to adjust the volume output on the speaker. If I use a microphone to record my voice also, this gives too much instrument audio mixed with the vocals due to the mike picking up the amplified instrument sound. Once I do manage to record something, I can't find any way to erase/delete the recordings other than removing the micro-SD card and taking it to my computer and erasing it there. It would be nice to be able to delete recorded tracks on the SD card without going to the computer to do it.

I am sort of ambivalent about this product. I am using it with an acoustic/electric ukulele. I wanted to use it to record instrumentals and vocals easily, and also occasionally use the amp in situations where I just need a bit more volume on my uke. Although it does do these things, it is quirky. When trying to record the uke, I can't adjust the volume output on the amp. This gives me a mix of acoustic sound and amplified sound in my microphone where I just want vocals. The only way I can find to avoid this is to plug in a headset in order to mute the amp. After recording a few tracks, I can't find any easy way to delete the tracks that I don't want. I have to remove the SD card and take it to my PC and delete the files there. Is there another way? I can't find it in the instructions.

Is it a fun product? Yes. Is it reasonably priced based on its quirks? Probably. Overall I give it five out of ten stars. It is a nice product at an attractive price point, but a few basic features could make it much better and easier to use.

Hello Clay,

Thank you for your review on PID 611700. Regarding deleting recorded tracks on the microSD card, unfortunately there is not a way to do that on the unit itself. They would have to be deleted via a computer as you are already doing. I truly apologize for any inconvenience this may have caused. I will pass along your feedback to our product team to be taken into consideration. For now, if truly unsatisfied with the amplifier, I can assist you in setting up an RMA for a refund as we offer a 30-day return policy with no restocking fee. However, S&H would be non-refundable. If you would like to continue with the RMA, please let me know and I will get that going right away. Thank you!

2 months in China

  • Travelin Prof,

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.

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!

Yet another (somewhat) useless piece of gear I own

  • Sev,

Pros: It works. Seems the battery life is pretty good. Looks ok too

Cons: Poor poor sound. So basically I turned it on when I got it and now before writing this review

This thing sounds like hooking your guitar to a baby monitor lifeless. I have a Strat so maybe humbucker-ists will be happier, they get a flat sound no matter what amp they use lol (joke guys, relax). I really don't care about the extras, all I wanted was a little bit of decent sound, just a little. I doesn't deliver for me.
I understand the limitations and I'm not really disappointed. I'm not sending it back because I will support this great company that offered me so many great products at incredible price

Hi Sev,

Truly sorry to hear about your experience with PID 611700. Does the audio quality remain the same when testing with different devices? Any improvements when switching out the cable in use? Please let me know so that I may further assist you.

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.
