The Blackstar Fly 3 is a portable, affordable practice amp that can run on a battery and come along anywhere you go. With three watts and 3-inch speaker, the Fly isn't meant to fill any stadiums, but still delivers compelling amp tones with built-in delay and EQ for good measure. Toss in a headphone output and line input for your phone or laptop, and there's not much this little guy can't do.
