Meet The Blackstar Mini Amp FLY3

Not long ago, the only practice amps available were low quality and strictly marketed towards beginners. Recently, players and builders have embraced the idea of low wattage amps, but high function practice amps.

Whether you are warming up backstage before a show, or playing quietly in a bed room at night, there have never been more options.

The Blackstar company is well known for its loud, tube driven combo amps and half stacks. Favored for their full, overdriven tones at high volumes, they have distilled those sounds down to just 3 watts.

Featuring a plethora of amp voicings, a portable construction, and diverse listening options, the FLY3 Mini Amp is well worth a look.

Digging Deeper Into the FLY3 Amp

Blackstar’s FLY3 is a 3 watt modelling amplifier meant for practicing and jamming along to your favorite songs. Modern specs like a MP3-in line and Infinite Shape Featuring give it a distinctly advanced feel for such a small, practice amp.

Even better, you get all that in a portable package that is battery powered. If you want to take your guitar practicing on the go, the FLY3 may be your best bet. Oh, and did we mention it costs less than half as much as some competitors?

Who Is The Blackstar FLY3 For?

Blackstar’s FLY3 mini amp is purely a practice amplifier through and through.

That makes it a great option for both beginners and veteran players, based on what you are looking for.

If you want to play your guitar late into the night, this is the amp for you.

With the emulated output jack, you can play your amp into headphones, without waking any neighbors or roommates.

If you’re a beginner, this is certainly a very budget friendly option for you to learn on, but it will surely never be a gig-able amp for you. So if live gigging is in your future, perhaps look elsewhere.

With your 3 watt practice amp you get an additional 3” speaker that perfectly matches your amp in size and finish.

This lets you get the full stereo sound experience whether you are playing MP3 music through the amp or jamming on your guitar.

Along with the necessary wire to connect the amp to the speaker, those are pretty much the only accessories you’ll unbox with your new Blackstar FLY3!

Blackstar Mini Amplifier Features
