The input level can be adjusted to your liking in the GT-100. Since different guitars and instruments have different output levels, it may be necessary to adjust the Input level. Here's how to adjust it.
1. Press SYSTEM.
2. Turn knob 4 (SELECT) to highlight the INPUT icon.
3. Turn knob 5 to adjust the level (-20dB - +20dB).
4. When you're finished, press EXIT. The new setting is saved automatically.
Note: The Input level parameter is "Global" for all patches.
