The Blackstar Fly 3 is a 3-watt mini practice amplifier designed for travel, backstage use, and home practice. Despite its compact size, it delivers high-quality sound comparable to larger amps. The Fly 3 features two channels, a tape delay simulation, and Blackstar’s patented ISF control, providing versatile tonal options in a portable format. Practice is made easy via the MP3/line-in connection, while the emulated line out with speaker simulation allows quick recording directly to a computer.
This little amp has a great sound, ideal for practice or music play. I'd definitely recommend it. I can't tell if the battery life is ok or not, because I don't use it this way.
