Empress Effects Tape Delay - Manual (Page 5)

Using Presets
The Empress Tape Delay ships with presets disabled, but can be set
to use either 2 or 3 presets, using the Advanced Configuration. Note
that presets cannot be used while the Tape Delay is in tap tempo
mode. The rest of this section will assume that presets have been
enabled and that the delay time toggle switch is away from the tap
mode.
To toggle through the presets, simply press the tap stompswitch.
The color of the tap led indicates the current preset. All changes
made to the controls of the Tape Delay will be automatically saved
to the current preset.
You can lock your presets, to prevent them from being overwritten,
by using the Advanced Configuration. When presets are locked,
changes made while the preset is engaged will not be saved.
