ZVEX EFFECTS Seek-TremThe Seek Trem is an eight stage sequencer controlled tremolo pedal. The controls are, from left to right, 4 8 6 step selector switch, speed (tempo), and 8 sequencer volume controls. All of the controls work in the opposite direction from conventional because the pots are smoother this way. This means you have to turn them to the left to make them louder, or in the case of the speed control, to make it faster. There is also a true bypass stomp switch
