The Boss FA-1 FET Booster is a guitar effects pedal that can add extra gain to your guitar signal, and can also help to shape the tone of your guitar. It features a FET (field-effect transistor) gain stage, which can add a warm and natural-sounding distortion to your guitar tone.

The pedal has bass & treble controls that allow you to adjust the EQ of your guitar signal, and a level control that can increase or decrease the overall volume of the pedal. The FA-1 FET Booster is a great choice for guitarists who want to add some extra volume to their sound, without sacrificing clarity or tone.

*Please note that these are not licensed copies of the pedals that they are immitating and whilst they are designed to acheive the same sound, there may be some differences.
