Joyo's new GemBox has all of these great-sounding， useful effects right out of the box: Chorus， Flanger， Phaser， Tremolo， Vibrato， Distortion， and Fuzz. Not to mention amp simulators and a flexible， modern-sounding drum machine. You have control over the key sound parameters with the expression pedal: it can alter modulation， drive， delay and gain， depending on the effect that is being used. It comes with the 9V Adapter and an Instruction Manual -- allowing you to dive right in and learn the key functions fast.

All told， this shining GemBox offers the incredible value and playability Joyo is famous for!
