New, Unused JHS Pedals Tidewater Tremolo JHS Pedals I never ended up using it after I bought it! It's a new, unused item. Introducing the "Tidewater Tremolo," which faithfully reproduces an amp tremolo that shimmers like water, with warmth and character! Controls consist of Volume, Mix, and Speed. Volume sets the overall volume of the Tidewater Tremolo to unity, below unity, or above unity. By turning the Mix knob towards the minimum value, the Tidewater Tremolo can also be used as a preamp boost. The Mix knob controls the tremolo's depth, and the Speed knob controls the speed of the tremolo, indicated by the adjacent LED. There are three small dip switches located on the back of the pedal's internal PCB.
