4 5 NOTES Slash’sAFD100Settings

Slash has traditionally been setting all the controls around 6 in both AFD and #34 modes. However, depending on the venue or stage acoustics, he fine tunes the controls usually finding his preferred settings between 5 and 7. The Power control should be adjusted to the desired volume. Very low power settings tend to benefit from slightly higher gain settings.
