MXR · pedal
The MXR Jerry Cantrell Firefly Talk Box is a limited-edition signature effects pedal bringing Jerry Cantrell's iconic talk box sound to pedalboard formats. Unlike traditional talk boxes requiring external speaker connections, the MXR features a built-in compact amp and speaker driver with a tube delivering the instrument's sound to your mouth for modulation and tonal shaping. Volume, Tone, and Gain controls enable customization of the talk box voice character and impact. The pedal is compact and pedalboard-friendly, designed for modern gigging convenience while maintaining the unmistakable sonic character that made the talk box legendary in Alice in Chains' music.
