GR-20 - Help create MicroKorg Digital Rock Guitar sound

[Syntheside]

hello I own a Roland GR20 and I was wondering how do you recreate the sound called "Digital Rock Guitar"? I have a Korg Microkorg and I want to make the Digital Rock Guitar on it. So how do I go about making it? Does it involve Square, PWM, Saw, Triangle or Sine Waves? And what effect makes it sound like it? Phaser or flanger?
