Chapter 4 The Effects Explained

OD/DIST (Overdrive/Distortion)

This effect distorts the sound to create long sustain. The GT- 6B provides nine types of distortion with two different custom settings.

■OD: Overdrive

This provides the warm, natural type of distortion that occurs naturally when you turn up the volume on a tube amp. This effect is often used as an amp pre-booster.

■DST: Distortion

This effect features a deep, powerful distortion that is difficult to achieve with amp distortion alone.

■FUZ: Fuzz

This effect gives an even more powerful and intense distortion than you get with regular distortion.
