Missing Link Audio is a Georgia-based builder of handcrafted guitar pedals, pickups, and amplifiers, founded by Mark Hooten. The company is collectively staffed by musicians, engineers, and former roadies, and has carved out a niche around classic Southern and British rock tones — most notably the Allman Brothers' Fillmore East–era live sound. Products are assembled in the USA and sold with a lifetime warranty.

The pedal lineup is heavily voiced around classic overdrive and distortion territory, with models including the Peacock Overdrive, the Eliminator Overdrive (a ZZ Top–styled tone machine, also offered in a Germanium V2 variant), the HotLanta Dual Drive aimed at Allman Brothers tones, and the AC/OD, a Plexi-style drive referencing AC/DC tones. Alongside the pedal line, Missing Link Audio produces the Mason-Dixon amplifiers and pickups, and the brand's designs often highlight op-amp circuit tweaks intended to mimic transistor-like dynamics.

The company distributes direct through its own shop and via retailers including Reverb and Guitar Center, with First Line Distribution handling exclusive UK distribution.

Missing Link Audio has 18 products cataloged on Equipboard, including Overdrive Effects Pedals and Fuzz Effects Pedals.
