Boomerang® E-155 Chorus*Delay – Software Version 1.1 – 7 Nov 2011 – Page
3
This knob is “speed sensitive” which means it takes bigger steps if moved quickly and smaller steps if moved slowly.
You can get where you’re going quickly and have fine, detailed adjustment when you get there.
When moving the knob very slowly the time will change but the clock display may not because there are many time
choices but only eleven lights.
Repeats Knob
This sets the number of repeats, or said another way, it sets how fast the repeats fade out. Some folks call this feedback.
Level Knob
NOTE
– This knob behaves differently depending on which delay style is selected.
1) With Clean & Tape styles it controls the amount of affected signal blended in with the dry signal.
2) With Reverse style it has 2 zones. From 0 to 8 it increases the affected signal until it is as loud as the dry signal. At
higher settings the affected signal level isn’t changed, but from 8 to 11 the dry signal is slowly reduced to zero. This
allows you to play a reverse lead live!
On/Off Foot Button
This is the foot button at the bottom left of the delay section. The delay tail will fade out naturally if the delay is turned
off with this button.
Tap Tempo Foot Button
This provides a way to set Delay Time with a foot button and is handy for live performance where your hands are busy.
Delay Time is set by two taps on the button. The nearby light will blink showing the tempo you tapped in.
Delay Style Button
This is the small button just to the left of the three Delay Style lights. It selects one of the three styles of delay
described next. Press & release to cycle through the choices. The current selection is indicated by a light.
Delay Styles
Clean
This produces a crisp, exact reproduction of the original signal. And when used with a stereo rig, Clean produces a
ping-pong
effect. The repeats alternate between the left and right channels. This sounds e-freaking-normous!
Tape
Sounds like the cool, but expensive and unreliable, tape units from the 60’s and 70’s. The repeats become warmer and
warmer. Nice!
Reverse
The repeats are played back in reverse producing a very eerie effect. Try it; you’ll like it! This style allows you to play a
backwards lead.
NOTE
- The Delay Level Knob works differently for Reverse delay. See “Level Knob” above.
3. “Clock” Display
The Clock Display, the ring of eleven lights with one in the center, has two purposes.
1) It shows preset information – the center light is green.
Each of the eleven numbered lights in the display represents a preset. The
active
preset is indicated by one of the lights
glowing green. This is the preset that is affecting your sound right now. The
selected
preset is indicated by one of the lights
glowing yellow. This is the preset that will be used when the Recall button is pressed & released.
2) It shows the values set by the knobs – the center light is red.
Whenever a knob is moved, the preset information will disappear and the Clock Display will show the parameter’s value
with one or more of the lights glowing yellow green. Two seconds after you stop moving the knob, the display returns to
showing preset info and the center light changes from red to green.
NOTE
- If the center light of the clock display blinks, the active preset has been altered.
NOTE
– When a knob is moved one “click” the display shows the parameter value but does not change it. The parameter
value will be changed on the following click(s).
4. Presets
What’s A Preset?
A preset is a “snapshot” of a customized sound. Each preset contains all the information necessary to return the pedal to a
particular setup or sound. When recalled, all parameters are set to the values they had when the preset was stored,
including Chorus speed, depth, mix, style, Delay time, repeats, level and style.
There are 11 killer presets programmed at the factory so you can immediately use your
E-155. See the “Factory Preset Parameters” table below for the glorious details.
