Blackstar FLY High Gain 3W Portable Mini Guitar Amplifier
The Blackstar FLY High Gain takes everything guitarists love about the award-winning FLY series and pushes it into heavier territory. Designed for rock and metal players, this compact 3-watt portable guitar amplifier introduces an all-new Nitro high-gain channel, delivering crushing distortion, tight low-end response and articulate lead tones from an amp small enough to fit in a backpack.
Whether you're practising at home, warming up backstage, travelling between rehearsals or simply looking for a great-sounding desktop amp, the FLY High Gain proves that huge tone doesn't require a huge amplifier. Despite its compact size, it offers impressive volume, exceptional clarity and the dynamic response Blackstar has become famous for.

Blackstar ISF Tone Control
A standout feature across many Blackstar amplifiers is the patented Infinite Shape Feature (ISF).
Rather than a traditional EQ, ISF lets you move continuously between two distinct tonal characteristics.
Turn one way for:
- tighter response
- scooped mids
- modern American-style tones
Turn the other for:
- warmer mids
- classic British character
- vintage rock sounds
This gives players enormous flexibility without needing multiple amplifiers or complex EQ settings.
Built-In Digital Delay
Integrated digital delay adds depth and ambience without needing external pedals.
Perfect for:
- solos
- ambient practice
- lead playing
- expressive clean passages
Simple controls allow quick adjustment of delay time and level so you can dial in everything from subtle slapback to spacious echoes.
Practise Without Disturbing Anyone
The emulated headphone output reproduces the sound of a miked guitar cabinet, making silent practice enjoyable while also providing a useful output for home recording.
Simply connect:
- headphones
- recording interface
- mixer
and continue playing any time of day without disturbing family or neighbours.
Jam Along With Your Favourite Tracks
Using the AUX input, connect:
- phone
- tablet
- laptop
- MP3 player
The external audio bypasses the amp's guitar EQ, allowing your backing tracks to remain clear while your guitar sits naturally over the top.
Ideal for:
- learning songs
- online lessons
- YouTube backing tracks
- rehearsing setlists
