Yes. Guitar pedals can offer a whole new world of possibilities to synth users. There are a ton of different effect pedals available, almost all of which can easily be plugged straight into your synth and controlled the same way you would control it for a guitar. In order to maximize the benefits of the effect pedal you choose, however, you should take care to adjust the output signal of the synth before it reaches the pedal. All guitars, keyboards, synths, and guitar pedals have 1/4" jacks that allow cross-compatibility. Even if a pedal isn't labeled for use with a synthesizer, it can still be hooked up to one.
