Crystal Clear, Full, Bright Tones in a Tiny Unit
Halina 18.05.2015
I had heard some great things about the Blackstar Fly 3 watt mini amp so I was very keen to try it. I was looking for the ultimate portable, battery operated guitar amp and I can confidently say, I think I’ve found it. This tiny combo has all the features you need for practicing and home performances. Its best asset is the lovely crystal clear sound it provides, which is in no way tinny.

The Fly 3 is a little smaller than the average box of 80 teabags. You can pick it up easily in one hand, making it extremely portable. The big sound is a surprise! The casing is well made; sleek and modern looking and the four main control knobs on the top (gain, volume, EQ and delay) are chunky and operate smoothly.

There are two channels, switchable at the touch of a button. I mainly use the clean channel. I have mostly played my Fender telecaster through the amp.I generally have the volume at about halfway up and the gain about a third. This is more than loud enough for me to sing along to, so that will give you some idea of the potential volume the Blackstar can put out. At this level, when I switch to the over-driven channel I get a nice, fairly subtle, crunchy sound with lots of bite. But of course, it can go a lot louder and more distorted than that. It really is quite amazing that these sounds come from this little box. You have to hear it to believe it.

The delay is of fantastic quality for a unit like this. I would say it is equal to using a good quality effects pedal. It ranges from a gentle reverb to a long very clearly defined delay.

I bought this amp about seven weeks ago and have used it a lot, yet it is still operating on the original set of batteries that come supplied with the unit, so I have felt no need to buy the power supply. I am keen to buy the extension speaker cab which turns it into a stereo unit, which must produce an even fuller sound.

Other features are a bright power on light (so you never leave it switched on by accident,) a headphone socket and a line in for an mp3 player. My tunes sound great through it and I also listen to audio books on it.

I just love the unique tone of this Blackstar amp. It’s very clear, bright and full. I’m a very happy customer.


Mini by name but maybe a little bit more by nature!

What do you do when the children have gone to bed, your partner is in the lounge watching TV and the only place to have a noodle on guitar at a reasonable practice volume is in the kitchen? You get a Blackstar Fly 3 mini amp!

No lugging your big amp from one room to another. Pop your Fly 3 on the table next to your lap top and jam along to your favourite music or learn something new.

The Fly 3 gives a clear punchy sound even at reasonable volume. You're not going to get tremendous bottom end, after all it's a small amp with a small speaker, but it's enough for it's intended purpose. I like the tape echo / delay, nice little feature, which also helps a bit as there is no reverb.

I have the ISF control at 12 o'clock position. Too much to the left and the top end is a bit too biting for my tastes and too much to the right and it gets slightly woollier. In fact all dials on 12 o'clock position seem right to me.

I put my little Behringer modeller / DI box in front of it and it comes even more to life and it helps the bottom end too.

It was the cheapest little desk top amp of them all but appears to be sturdily built.

All in all, just what I expected - and fit for purpose!


Pretty good practice amp
EugeneLugovoy 04.03.2021
I have bought this small 3w amp to use as practice amp and small home performances. I've checked a lot of videos to compare combo amplifiers in line of 3w-5w and have to say FLY 3 was on top in comparison to marshal, orange and few others; the sound/price is fair. Nice presets of EQ, not so bad OD and simple&good delay - all you need for practice. The batteries goes long enough (I have used them without changing about 6 months). So, for home practice or learning the guitar this amp is very good.
But, if you want to have small mobile amp not only for practice, but for your individual performances, you have to look at another amps in a bit higher power range 7-10w and abilities. In other words, after I have tried BOSS Katana Mini (7w) and Yamaha THR5, the sound of Blackstar FLY 3 looks a bit ugly for me.
Anyway, I really like this amp and I rate it as very good, I remember the time I brought in local studio for playing and some musicians just laughed on, but when I connected it into main mixer via microphone and we tried to play some rock'n'rolls, they said - Oh, my... this sound not so bad.
That's a I wanted to say, hope this can help you to find your lovely amp


Great sound
Dutchy- 04.06.2021
I was a bit skeptical of purchasing this amp at first, I must admit. 'A battery powered amp that sounds good?', just didn't seem to make much sense to me. However. I am absolutely blown away. I recently moved into an apartment, so I didn't want to use a bigger amp and annoy all the neighbours. This amp is a godsend for that, it has a good level of volume, but would perhaps be lacking for a larger living space. Bedrooms and apartments are prime for this amp.

Great features, the gain could have been a bit more for my taste, but it's nothing a bit of overdrive can't fix! Delay is fine, as is Blackstar's ISF tone stuff. The switches and knobs feel like they're good quality, nothing is loose.

Of course it's a bit plasticy, nothing wrong with that for the price and the quality of the electronics inside though. Can't really find a fault with it for my usage. It really isn't that loud though, which is perfect for me, but some people may want something that's got a bit more power.

Overall great, good price, good quality, good controls. Can't fault it myself, especially for practicing at home in a small room. Batteries are meant to last a long time, although I can't comment on that as of yet. Highly recommended!
