If you’re into the Pulsar and Stereo Pulsar pedals, then you’re going to dig the Electro-Harmonix Nano Pulsar. The pedal offers both Triangle Wave and Square Wave modes shapeable by the Shape control (obviously), and then the Rate and Depth knobs to further tweak your tremolo. The Electro-Harmonix Nano Pulsar offers both mono and stereo modes, and has an LED that pules in time with the chosen tremolo rate should you need the visual cue.
