Eddie Breckenridge (born Edward Carrington Breckenridge on November 15, 1979) is the bass guitarist of the band Thrice. Breckenridge joined Thrice having virtually no experience playing the bass (he was a skating buddy of soon to be singer/guitarist Dustin and lead guitarist Teppei). He soon convinced his brother Riley to join as the band's drummer. Breckenridge has an elbow problem that prevents him from turning over his left hand fully (making fingering the fret board more difficult than usual). Breckenridge also played bass in the band Angels & Airwaves.
Breckenridge has contributed ambient noise to an experimental track on Frantic Mantis's debut album via internet collaboration, Bass and acoustic guitar in a Dinosaur Jr. tribute album Felled Trees Where We've Been, and plays bass for the reunited 90's Emo group Knapsack.
