The Mooer Triangolo is a tremolo pedal packed with features in a small size. The Triangolo features advanced digital algorithms, providing overwhelming control for a pedal of this size. A toggle switch allows you to select tremolo shapes: triangle wave, square wave, and sawtooth wave. The DEPTH control widely controls the depth of the tremolo. There are two ways to set the tremolo speed. One is the classic method of using a knob, as with many tremolo pedals. If you want to set the speed once and leave it, this is the simplest method. Furthermore, the Triangolo can also control the tremolo speed using tap tempo. The SUB DIVISION knob allows you to set the speed to match the rhythm pattern. Tap tempo can be set using the TAP button switch on the unit or a footswitch. Also, setting SUB DIVISION to X allows for random tremolo settings. The tempo and pattern become random, creating interesting effects.
