TREMOLO PEDAL Faithfully recreate the tremolos of a Vox or Fender Blackface with JHS quality with the same warmth and character you expect from a vintage amp. With only 3 controls (Volume, Mix, Speed) you can use the Tidewater as a Boost Preamp, control the depth of the tremolo and its speed, indicated with the LED. Inside the pedal there are three DIP switches with which you can change the speed depending on its position. It operates at standard negative 9V and consumes 3mA.
