Setting Phase and Anti-Feedback
The Phase and Anti-feedback controls can be used to restrict the two most
dominant feedback notes, allowing greater volume before feedback than
otherwise possible. In most cases, the Phase switch is used to control the lower
dominant note while the Anti-Feedback notch is used to control the higher.
1. Start with the Anti-Feedback control turned down completely.
2. Turn up the level of the amp until feedback begins.
3. Flip between the two Phase positions. Each position will produce a
different dominant feedback frequency. Listen to the frequencies and
select the Phase position which allows the higher note to feedback while
subduing the lower.
4. Adjust the Ant-Feedback clockwise until it subdues the frequency of the
higher feedback note.
Since optimal tone is a matter of taste, one can also experiment with reversing
the order, using the Phase switch to control the upper feedback note and the
Anti-Feedback notch for the lower.
