distance. The best way to come near without touching the strings is to hold
the Resonators Head at right angles to the guitar neck.
The red or blue lights intensity depends on the signal that drives the
Resonator. The brightness decreases when the string vibration dies away.
Moving the Resonator closer to the strings amplifies the vibration whereby the
brightness increases again. To drive the Resonator sufficiently, the gain at
your guitar should be turned up to maximum. If you like playing often with
reduced gain than this must be compensated with the gain of the Resonator
Box. However, this will increase the unwanted feedback sensitivity at turned
up guitar volume, so that eventually a reasonable compromise has to be
found.
4.2 Harmonics control by positioning the Resonator
The nice thing is that you get different harmonics depending on the
Resonator Head position along the neck. This is done by moving the guitar
neck with your body or with a direct arm movement. Players with low hanging
guitars prefer moving up the guitar neck to the Resonator (the typical Hendrix
like position). Players with higher hanging guitars just need to move their
body to the Resonator. However, the important thing is to come near enought
without touching the strings. By the way: As we all know, new strings are
essential for rich string harmonics. This holds true particulary with feedback
harmonics !
4.3 Changing harmonics by phase shifting
Phase shifting is another way to switch between basic and harmonics
feedback. The phase position is indicated by the red and blue light. Phase
shifting can be done as a preset or for changing the feedback tone while
playing.
4.4 Some string vibration basics
Perhaps you would like to understand more about the dependencies of driven
feedback harmonics, Resonator position, phase and pickup selection. In that
