Synth pedals are a must-have for the experimental guitarist. They can unlock the door to a massive variety of new sounds that will inspire creativity and expand your range of styles. Synth pedals emulate the sound of a synthesizer (as the name implies), allowing your guitar to become a musical multi-tool.
One of the best things about synth pedals is their functionality to simplicity ratio. You can get a huge amount of versatility out of these stompboxes with very little technical knowledge. Just plug in like any other FX pedal and away you go - you are instantly the next Jean-Michel Jarre. That's not to say that these pedals are basic by any means - they still offer a great degree of control over your sound should you choose to utilize it.
