The Skitter is one of the most unique and useful pedals I've ever had.
It's described as a "Reverbolo" - half reverb, half tremolo.
It has all the critical functions a modern player needs from a tremolo and reverb unit. But what sets it apart from two regular individual pedals or similar combo units, is its special ability to mash the effects together and offer you an entire new palette of tones and textures.
In this short clip I used a simple, dry, digital synth and ran it through The Skitter to make it sound alive and in motion.
Don't take my word for it, try one and see why it's a pedal board must.
