Jimbo Wallace is an upright and electric bass player, vocalist, and songwriter in the psychobilly and rockabilly genres. He has played bass in the Reverend Horton Heat band since 1989.[1] He plays using the percussive rockabilly/psychobilly bass technique known as slap bass, in which the strings are pulled away from the fingerboard until they snap back, and the strings are rhythmically slapped against the fingerboard. The German rockabilly bassist Didi Beck cites Wallace as one of his influences.[2] Concert reviews take note of the stunts that Wallace does with the bass, such as throwing it into the air[3] or playing it on its side while Heath stands on top of it and plays guitar.[4] He has a signature tiger-striped upright bass manufactured by King Double Basses.[5] He has been an endorser for Gallien-Krueger bass amplifiers. On stage, he uses a 4x10" cabinet and a 1x15" cabinet with a GK amp.
