In their recent review of the 2017 NAMM Show, Vintage Guitar magazine singled out roots blues guitarist Justin Johnson for his demos at API's booth. Johnson played his 3-string shovel guitar through API's new TranZformer GT Guitar Pedal, never failing to draw a crowd of listeners. Thanks to Justin Johnson and Chris McLernon for their wonderful demos of the TranZformer GT Guitar and LX Bass Pedals, respectively, and thanks to Vintage Guitar for the shout out.
