Blackstar amPlug2 Fly Guitar Headphone Amplifier

Gearank Recommendation

The Blackstar amPlug2 Fly appeared on our recommended list for Guitar Headphone Amps from December 2021 until June 2022 when it was replaced by higher rated models.


Blackstar is well known for their high-gain amps, and for the versatility of their ISF (Infinite Shape Feature) control. The amPlug2 leverages these strengths by packing all them inside a compact bug-type headphone amplifier.

For something small, it comes with the best features found on the popular Blackstar Fly mini-amps, including 3 selectable channels (clean, crunch & lead), and the ability to change the voicing from British to American style via the ISF knob. It even lets you use effects that include reverb, delay and chorus right on the unit.

For compatibility with different body types, Blackstar designed the plug to be foldable, and allows for up to 180 degrees rotation.

It runs on AAA batteries for up to 17 hours and has an auto power off feature for longer battery life.

Finally, it has an Aux in jack for jamming along with your favorite tracks.

This is a no brainer for those who love Blackstar amps, and it is also a good budget friendly way to get to know the brand. Leaving the brand issue aside, the versatility of this headphone amp makes it standout from what others have to offer.

Although this was previously on our recommended list there are now more highly rated options available which you can see in our guide to The Best Guitar Headphone Amps.

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.
