BLURB:
I think this is the most amazing distortion unit ever made. It has a huge scope of distortion from “Gently Warming” to “Cut into sharp thin slithers and ram into your eyeball”. It’s strength is not just distortion, but also in Wave Shaping. You can patch a pure Sine Wave in and get a Spiky Saw Tooth out.
