MXR Phaser & Flanger. What am I missing? in Helix Posted November 15, 2018 Run the phaser and flanger before the amp. Distortion in the amp seems to make the sound a little more pronounced. What phil_m sad above it true. For script phase I change the speed to 1.5. That's all I change and it sounds great. For Flanger I set everything at 40% except the Regen I set to 100%. This is pretty much the exact EVH sound to my ears.
