Fender Mustang Micro Headphone Amp

Not the cheapest but very likely the smartest choice if you are looking for a versatile, easy to handle, pocket-sized portable amp to serve your practicing needs.

This quality made device gives you full freedom to play and enjoy a plethora of rich sounds wherever and whenever you may wish to do so, as it only requires a charged battery (which will serve you at least for 4 hours) and a set of (wired) headphones. (BTW, I’ve been frequently using a standard set that comes with almost every smartphone and even so the results are more than satisfactory.) Should you wish to play along a backing track, the Bluetooth feature is readily available with a switch of a button.
I realize that the above might sound more like a manufacturer’s ad than one’s personal opinion based on experience, but I was really impressed and got more than I had expected with this little fellow. Well, OK, I do miss the possibility to connect wirelessly to a set of headphones, but … you can't allways have it all, can you :)

Unfortunately, most probably because of the current pandemic and its various consequences, delivery time is painfully long but the gadget is well worth waiting for.

Very happy with this purchase.

By selecting the studio preamp, it is possible to use the Mustang Micro with a bass guitar. I've tested it with my passive Fender Jazz and Precision basses and they both sound great through it. For best volume, I strongly recommend using low impedance headphones. I've tested it with 16 ohm and 20 ohm ones and 1/4 volume was more than enough to hear myself comfortably. Playing with lower volume also has the advantage to extend battery life.

The bluetooth connection is a great plus as it allows me to jam on my favorite tracks, play while watching video lessons and so on.

I had another pleasant surprise when I almost accidentally connected the Mustang Micro to my Android 14 Samsung Galaxy A9+ tablet through an USB-C to USB-C cable: by using virtually any app able to record sounds (like the camera app), the tablet automatically records what comes out from the Mustang (which the tablet recognizes as an "external microphone"). The output includes the sound of the bass but also the track sent to the Mustang through the bluetooth connection.

In conclusion: this is an amazing little tool and it is strongly recommended also for bass players!

This finally replaced my 22 (!) year old Korg Pandora as a practice tool, to be used with headphones.

The preset sounds are great and offer a nice range of amps and effects, suitable for practicing and having some quick fun.

Suitable for Blues, Funk, Rock, Hard Rock etc. but not so much for the more extreme sides of Metal (might need to look elsewhere if this is what you wish to use it for).

You can also connect your phone via bluetooth to play backing tracks on it and jam (or practice exercises), which is really cool.

The device construction seems reasonably solid (we'll see in the long-run)

Overall, a great product, with a reasonable price.

I got this little headphone amp to take with me on the road. It's very portable, USB-C rechargeable (so you don't have to take another cable or batter with you) and all you need to do is plug it into the guitar as well as some headphone, turn it on and you're good to go.
The best surprise was the sound. I'm a rookie to amps, but the quality of the tone blew me away, to the point where I prefer using it for practicing in my bedroom. It's really easy to use, sounds great and has enough options to tinker with the tone.
The USB interface works good, but I had a tiny bit of delay on my setup with my M1 iPad and Amplitube. Not much, but definitely noticable, so probably not ideal for using it to model amps via a computer or iPad. The sound seemed fine otherwise, so probably still good for recording a track at home, with the headphone output to monitor sound.
One thing that would've made this thing even better: I wish it had a built-in tuner. But otherwise, I really like it!

Lots of sounds, most of them good. Feels good in use too, though it's a little awkward to see which amp model or effect you're on without referring to the provided reference card, and twisting your guitar to find the lights.

Outside that, it delivers what you want in terms of tonal variety and quality. It doesn't sound like an amp in a room, but it's not a million miles off either, it surprised me a bit. I would say it flatters your sound well - might be a touch of compression - but in a pleasant way.

The Bluetooth element is great, but bear in mind that's for streaming a backing track not using bt headphones, you have to plug the headphones in.

Overall, I'd recommend it over something like an amplug but be aware it's not going to blow your mind with faithful recreations of classic amps. It come close for such a small device, and the recording element via a computer is quality, but you aren't going to replace your Twin with this for anything beyond quiet practice sessions.

Still recommend it, for the price, the size, it's very good.

It is great tool for practising without disturbing others.

Very simple to use. No need to connect to an app and go through 5 different screens that have 50 different knobs each one. Also no need for a computer. Just plug and play.

The sound experience can vary a lot (from really nice to really bad) depending on the headphones and the guitar pickups. I would recommend buying a good pair of headphones if you don't have one.

The 4 clean channels sound very similar. I would prefer 3 clean channels with different tone, and additional crunchy tones.

I feel Fender missed the opportunity to have a tuner built-in.

Even though it is made of plastic it doesn't feel cheap.

How come nobody even mentions the crazy latency problem? I bought this for my silent midnight practice sessions, but it doesn't hold up quite well. If you're into any kind of shredding (fast solos, tremolo picking, sweep picking, etc.) the latency with any reasonable distortion level just makes it impossible to play (I'm using high-quality wired headphones). If you are using it as "clean amp", then the delay is much better, but then again, you might as well just listen to the string acoustics if you want to practice silently and not use any distortion or effects...
Also, the higher the gain, the worse it starts to sound, so again, this isn't for metalheads.
I'm very disappointed with this purchase, the huge latency definitely limits what kind of songs/techniques I can practice with this... But it might be okay for just slight jamming or other, more latency-tolerant genres. Honestly, it's hard to believe that all those YouTube "reviews" are not sponsored, since everyone is dead silent about this while this is the first thing that hits you when you try to play...
I will give a try to the Vox next time, let's see if that's any better.
