The Molo-Trem is a tremolo that uses a photo-electric circuit, sounding like one of the tremolos you can find in vintage tube amplifiers. It is flexible but easy to use. Three simple controls allow you to adjust Rate (Speed), Depth (how much the volume fluctuates), and Wave. The Wave control is great because you can change it from a subtle triangle wave to a drastic square wave. This way you can achieve the classic tremolo sounds that we all know and love as well as the more modern “stutter” sounds to create incredible rhythmic pads, especially if combined with a cool delay sound (Like the FILTER delay of our QUATTRO pedal)
