In great condition, works perfectly. 

Not just a phase. The Boss MD-200 Modulation Pedal gives you all the mod effects you could ask for. And then some. World-class effects. In one compact pedal. With 12 modes to choose from, you've got an arsenal of modulation at your disposal. Dial in Chorus for those '80s leads. Or create vintage quiver with the Tremolo setting. The MD-200 is a huge boost to your sonic repertoire. Take control and tap in rates with a built-in tempo switch. Making sure you're always in time. While a versatile insert function means you have a wealth of patching options available. You can have your say over pre and post mod processing.
