An absolutely immaculate example of the highly sought after Boss FB-2 Feedback / Booster pedal. Becoming increasingly rare, this thing is cool as heck.
The BOSS FB-2 Feedbacker/Booster gives dynamic, and versatile boost in a simple pedalboard size friendly format. Boost cleans to go from mellow to sparkling, and can add extra grunt to your high-gain playing, the FB-2 is great for both. However, the FB-2 is more than just a booster pedal as when you hold the pedal down the FB-2 can generate a natural amp feedback, which is perfect for adding an air of controlled chaos to your playing.
