Death By Audio 2012 Total Sonic Annihilation Feedback Looper Effect Pedal - UsedThe Death By Audio Total Sonic Annihilation is a dead simple feedback looper that causes whatever pedal you put into its loop to cycle back on themselves, feeding the output back into the input as much or as little as you want. This is the first version, before DBA added phase and boost options. This pedal is in good condition and ships as photographed. No original box is included.
