USER MANUAL
PAGE 7 OF 12
G. CV Remote Speed
- Allows for control of the
unit “speed” function using control voltages,
including any TRS expression pedal (100K
Ω
impedance recommended). Connecting a CV
source to this input will disable the “Speed” control
(R).
H. CV Remote Feedback
- Allows for control of the
unit “feedback” function using control voltages,
including an expression pedal (100K
Ω
impedance
recommended). Connecting a CV source to this
input will disable the “Feedback” control (X).
I. Chorus Cancel
- Allows for bypassing of unit
functions with an external footswitch. Connect a
one-button TS footswitch to bypass the chorus. It
is also possible to use a two-button TRS footswitch
(latching type) however the ring switch will not
have any effect.
J. Echo / Reverb Cancel
- Allows for bypassing of
unit functions with an external footswitch. Connect
a one-button TS footswitch to bypass the echo
only, or a two-button TRS footswitch (latching
type) for bypass of the echo (tip) and reverb (ring).
K. Output
- Connect to an amplifier, audio
interface or additional effects processors.
L. Output Level
- Sets the output level of the front
output Jack (K). Note this does not set the output
level of any of the rear outputs, these are fixed at
high output.
M. Echo Mode
- 7-position selection of the unit’s
playback heads. Please consult the following table
for a guide to these settings:
Mode 1 - Head 1 (short) [56 - 221ms]
Mode 2 - Head 2 (medium) [121 - 477 ms]
Mode 3 - Head 3 (long) [187 - 800 ms]
Mode 4 - Head 1 + 2 (short + medium)
Mode 5 - Head 2 + 3 ( long)
Mode 6 - Head 1 + 3 (short + long)
Mode 7 - Head 1 + 2 + 3 (short + medium
+ long)
The Sound On Sound playback head can be
engaged over all the above settings.
N. Guitar / Line Volume
- Adjusts the gain for
input (F).
O. Chorus Rate
- Sets the rate of the chorus.
P. Chorus Depth
- Sets the depth of the chorus
by changing the amount of pitch modulation in the
affected signal.
Q. Reverb Volume
- Controls the volume of the
spring reverb.
R. Speed
- Adjusts the echo rate, corresponding
to the heads selected with control (M). Turn
counterclockwise for longer echo times, or
clockwise for shorter.
Please note: This is controlling the physical
motion of a motor and echo times will ramp up
or down gradually when adjusted, with the pitch
of any repeated sound being raised or lowered
accordingly.
S. Echo Volume
- Adjusts the volume of the
echoes mixed into the overall output signal. Turned
all the way to maximum, the echo volume is slightly
louder than the dry signal. Please note: This does
not affect the individual head outputs at the rear of
the unit.
T. On / Off
- Supplies power to the unit.
U. VU Meter
- Indicates the input signal volume.
The loudest peak signal should go “into the red” for
optimal signal to noise ratio.
V. Bass
- Cuts or boosts the bass frequencies of
the overall output. 12 o’clock is “flat”.
W. Treble
- Cuts or boosts the treble frequencies
of the overall output. 12 o’clock is “flat”.
X. Feedback
- Adjusts the amount of regenerated
signal. Please note: Setting this control past
12 o’clock will likely result in self-oscillation.
Additionally, using multi-head echo modes at
higher feedback settings will increase the likelihood
of self-oscillation.
