The Warp drive overdrive has been specially designed to sound like a vintage Marshall Plexi. It delivers a warm tubey overdrive from a slight crunch similar to a valve amp on the verge of breaking up, to a fully saturated overdriven valve tone of a mid 60’s plexi. It is unique in dynamics and nails the tones of ‘ZZ top’ and ‘Angus Young’. You simply dial in the desired level of drive using the ‘effect’ control, set your tone and then adjust the volume to suit. It also has a 'bass boost' switch.
