Using Pre-Delay and Feedback
8. Now that we have the basic HALL sound setup, we can make the reverb sound
larger just by increasing the Pre-Delay time: the time it takes for the reverb wash
to begin after you have a played a note.
9. Turn the Pre-Delay time clockwise to increase the delay time. You will hear, as
you increase the Pre-Delay time, after playing a note it takes longer for the
reverb wash to kick in. Having a longer pre-delay time can give the listener the
impression of a larger space.
10. As you turn the PRE-DELAY knob past 12 o'clock you will notice that the pre-
delay time gets quite long, up to 2 seconds at the maximum setting. Leave pre-
delay set to a longish delay time, maybe 2 o'clock.
11. Now turn the FEEDBACK knob up to about 12 o'clock, you will hear the reverb
wash repeat numerous times. In this case the same note is being repeated
through the delay block many times, each time being fed into the reverb block.
12. Try turning the REVERB TIME knob down to full counter-clockwise, with this
setting you can hear discrete reverb echoes.
13. In addition to using the PRE-DELAY knob to set delay time, you can tap in a
delay time using your feet. Tap the TAP/INFINITE Footswitch two or more times
and the delay time will be set to the average time between taps.
Accessing Infinite Reverb Instantly
14. Now turn down both the FEEDBACK PRE-DELAY knobs back to full counter-
clockwise.
15. Set the REVERB TIME knob to 12 o'clock.
16. Play a note, the reverb should decay after a couple of seconds.
17. Now a play another note. While sustaining the note, press and hold down the
TAP/INFINITE footswitch. You should hear the reverb wash does not decay.
18. At this point you can play new notes over the reverb wash, without adding to the
reverb.
19. Release the TAP/INFINITE footswitch to allow the reverb to decay.
Basic Echo with Tap Tempo Use
1. Use the same connections as in the steps above.
2. Turn the MODE knob so that the ECHO LED is lit.
3. Turn the following knobs to 12 o'clock: BLEND, DAMPING/TONE, FEEDBACK and
PRE-DELAY.
4. Turn the REVERB TIME knob down to full counter-clockwise.
5. At this point, if you play a note, you should hear discrete echoes follow your note
instead of reverb.
6. You can set the delay time by turning the PRE-DELAY knob, clockwise for longer
delay times, counter-clockwise for shorter delay times. The maximum delay time
is 2 Seconds.
