When switched to Overdrive, the FLY 3 provides a surprisingly rich and crunchy tone that holds up well for rock and classic rock styles. While it lacks the depth and power of a larger amp, the sound remains crisp and defined, and the ISF control allows you to shape the tone to fit your preference.

The delay effect is a standout feature for such a compact amp, adding a layer of fullness that compensates for the small speaker. While it’s not as dynamic as a dedicated pedal, it’s perfect for adding texture during practice sessions. The amp’s 3-watt power rating is modest, but the volume it achieves is impressive considering its tiny speaker.
