The Electro-Harmonix Super Pulsar is an analog tremolo that can take the shape a sine, triangle, or square wave while allowing for unique rhythmic patterns via an onboard sequencer. It also has controls for Shape, Depth, and Rate. A Tap footswitch and Tap Divide button help it play in sync on the fly, while the Mode/Preset footswitch toggles between five expression modes or enables access to eight presets. The envelope section gives dynamic control over depth and rate, which can increase or decrease with input signal. Learn more at www.ehx.com.
