The Blackstar Fly 3 is a combo amp designed for portable use, rated at 3W and equipped with a 3" speaker.

Weighing in at just less than 2 lbs, you can literally take this amp anywhere, and since it can run on 6 x AA batteries or on an optional 6.5V DC power supply, you can play with it wherever you want to take it.

More importantly it's not just any generic amp, because it carries with it Blackstar's IFS (Infinite Shape Feature), which lets you change the voicing of the amp via a single knob.

Other features include having an MP3/line-in jack and headphones out with speaker emulation.

All these features make it ideal for use during trips and hotel stays, especially when paired with a travel guitar.

As expected, it features Blackstar's ISF (Infinite Shape Feature), which lets you change the amp's voicing from American to British with just one knob.

The Blackstar Fly 3 is a nice portable battery powered amp for those who are into Blackstar's brand of dirt and high-gain tones.

About Blackstar

Founded by former Marshall employees, Blackstar has grown to be a reputable amp manufacturer with its own identity. These days, it is able to go toe to toe with the biggest brands in the industry, thanks to the innovations they introduced into their designs. Their most popular innovation is called ISF or Infinite Shape Feature, a single knob that lets you shift the voicing of your amp from American to British amp flavor, and covering everything in between. Blackstar is well received for their amps' high gain tone, which works well with modern rock and metal styles. Richie Sambora, Neil Schon, Jon Gomm, Sammy Haggar and Ozzy Osbourne are just a few of the many popular artists that use their amps.
