Powerful little amp. Fits a purpose perfectly.
I bought this for my boy’s guitar lessons. He’s 11 and has to carry it with his guitar. It fits neatly in his bag and it’s at all heavy. The battery won’t last a huge amount of time, and it can sound pretty bad once the battery starts to go, but you can buy a power cable if you don’t mind being stuck near a socket. It is amazing for what it is though, it kicks out a great sound, has overdrive which is a handy feature, is portable and even has a belt clip! Plus it has a headphone socket too. I use it sometimes while I’m sat on the couch trying to learn to play too, just because it saves me dragging out the big Marshall, plugging it in, and then exposing my neighbours to some of my hellish learner screeching!

Great little amp, especially for the price and portability
I have this amp on my desk as a larger one wouldn't be feasible. I originally used batteries as i didn't have enough plug sockets to plug the amp in, but it went through a battery pretty quickly, so i managed to get it plugged in. I did initially use the Overdrive mode, which was ok, it wasnt amazing, and there was very little adjustments you could make, but it was useful, but now i just use the clean tone as i have my pedals setup under the desk. Overall the sound quality is good; about as good as you could expect from a small amp, and i have no issues with it for my use. I would definitely recommend this as a gift for someone who plays an electric guitar, since, even if they already have an amp and won't use this as their main amp, this is a useful thing to have since it is so portable and can be battery powered, because they will use it at some point, and will appreciate the gift.

For the price, it is pretty decent. Just a bit too light for its own good
This is my first example of a mini amp like this so not much to compare it too however initial thoughts are that it works well for the job it is intended for considering the price being charged. Only used it via battery power so far but despite the small size the sound kicked out is fine for my first forays into learning the guitar (and I'm sure my neighbours are happy I have nothing louder!). Being honest it looks and feels cheap, but then to be fair, it is! Only complaint is that it is incredibly light, in fact, too light - I find that when you have a lead plugged in the weight at the front has a habit of making it fall over. I'd recommend using it with an L-shaped jack to stop that happening.

Big sound. Great fun
Great little amp for practice and fun too. I use it with my Electro uke. Works a treat and can walk around with it clipped to pocket or belt. It's not for concert use so ignore any reviews that complain about the sound or how loud it is. In a normal size room I don't even turn it up to the highest volume. Also has a choice to use distortion 😄 For the money its well worth it. 🎶🎵🎤🎼🎸

Always wanted a Marshall amp
Eldest son wanted a cheap portable amp for jamming session and camping. Fits the bill. Only negative is the kettle whistling/buzzing. As a novice at amps happy to live with due to price and size.

Marshall MS4 Micro Amp
I bought this mini amp for practising in my flat. I have my guitar into an effects unit with that going into the amp. The amp is made of plastic but is well constructed and feels like it could survive a drop or 2. For such a small amp it does pack a bit of a punch and is better than I expected. It's definately loud enough for my flat. Sound quality is pretty good if slightly on the trebleish side. The range of tones available are not too bad at all and when used with the effects processor can produce a huge variety of sounds. The amps dymensions are 10" height, just over 4" wide and 2" depth. Weighing in at 0.5kg it's light enough to carry in a large pocket if your ever going for a jam at a mates house. Another positive point is that it runs off a 9v battery. Very handy! At £29 I'd recommend this no problem. If it ever breaks I'll use it as an ornamaent. Lol

Good quality amp
Good product, looks great attached to electric drum kit. Sound is decent quality. Had to buy cables and adapters separately.

For the price it is obviously not going to sound absolutely amazing but it still sounds good, my husband and I got it for our son so he could play anywhere and it works good for him. Without having to lug around a massive amp, I call that a win.

Got this for my son who uses it on with his electric guitar. He absolutely LOVES IT! I love how there is a little jack for his headphones as well. It looks amazing with all his guitar and sound equipment.

Sound is goo for small speaker, however, when the guitar is closed to it a harsh sound comes out very annoying
