The Molo-Trem utilizes a photoelectric circuit, it sounds just like one of the tremolos you could find in a vintage tube amp. The pedalis flexible yet easy to use. A simple three knob control allows for adjustment of Rate (Speed), Depth (how much the volume fluctuates) and Wave (hard or soft sounding). The Wave knob is useful because you can change it from a subtle triangle wave to a drastic square wave. This way you can achieve the classic tremolo sounds we all know and love as well as the more modern "stutter"sounds to create amazing rhythmic pads, especially if combined with adelay sound (like the FILTER delay from the JF-318QUATTRO pedal). Protective Flip Cover All of the Ironman series pedalsfeature a toughplasticcover that flips over the controls to protect your carefully dialed in settings from wayward feet, effectively offering a practical setand forget tone solution! Compact Mini-pedal Form Factor Advances in circuitry design have made itpossible for guitar effect pedals to be built in compact enclosures that literally fit in the palm of the hand.
