The Boss FB-2 Feedback/Booster isn't just a simple boost pedal - it's expressive, dynamic, responsive, and smooth. Use the FB-2 to transparently boost your sound or use it to create an extremely natural amp feedback. With only four highly intuitive controls, you can control the transparency, tone, and level of your boost or feedback. If you want versatility in your boost pedal rather than just plain, clean gain, the Boss FB-2 is a clear choice.
