Expandora is an American builder of guitar effects pedals that continues the legacy of the Bixonic Expandora, a Japanese-made boutique distortion pedal from the mid-1990s known for its round, hockey-puck style enclosure and multi-mode voicing. The original Bixonic circuit offered Crunch, Overdrive, Distortion, and Fuzz modes selectable via internal DIP switches, and earned a cult following among players looking for a wide range of gain textures in a single box. Under the Expandora Pedals name, the brand now manufactures the pedals in the United States.

The current lineup centers on the Expandora Vintage Reissue, which moves the mode switches to the face of the pedal and incorporates tweaks to the original schematic for improved headroom. The range has expanded to include the Expandora Squared and Squared Custom, which use larger enclosures to accommodate vintage chipsets and extra switching options, along with gold and silver limited edition reissues. The brand also builds the Forbidden Fuzz and Forbidden Fuzz Bass, extending its voicing into dedicated fuzz territory for guitar and bass players.

The original Bixonic Expandora was associated with players such as Billy Gibbons of ZZ Top, Joe Satriani, and Bootsy Collins, and remains a reference point in discussions of boutique distortion pedals.

Expandora has 4 products cataloged on Equipboard, including Fuzz Effects Pedals.
