QUICK START GUIDE
This knob controls the phase
of the right channel oscillator
in relation to the left channel
oscillator. With the knob at 0°
L and R outputs are sync’ed,
and at 180° they are totally
panned.
For intermediate values
multiple stereo schemes can
be obtained.
This stepwise knob selects
among 8 possible modulation
shapes:
1- Sinusoidal
2- Triangular
3- Square
4- Reverse
5- Exponential
6- Symmetrical valve
- fast attack
and slow release times
7- “Hot” asymmetrical valve
8- “Cold” asymmetrical valve
Shapes 6, 7 & 8 recreate the
shapes of a vaccum tube
oscillator
It’s the intensity of the
modulation, and acts as a
MIX control.
Controls the speed of the effect.
This stepwise knob selects
among 4 time divisions and 4
rhythmic patterns.
The time divisions multiply the
RATE by 1, 2, 3 & 4, or
equivalently, subdivide the
tempo of the effect by 1, 2, 3
& 4.
The rhythmic patterns are
sequences of figures and
silences that modulate the
input sound.
It’s a TAP TEMPO switch to
precisely set the speed of the
effect.
2 consecutive TAPS set a new
tempo, and additional TAPS
lead to better precision on
the desired tempo.
The red led indicates the
current tempo.
Enables/disables the effect.
The white led indicates that
the effect is on.
In this mode TRUENO becomes an oscillator, rising the speed of the effect to a
range of frequencies that mixes with the input audio. So the effect turns from
a conventional tremolo into a kind of Ring Modulator.
To enable/disable this mode, press and hold TAP TEMPO switch for 1 second.
The fast blinking of the red TEMPO led indicates that the Dissastro Mode is on.
The frequency of the modulation is controlled by the RATE, through the knob
or ideally using an expression pedal.
Expression pedal input, that
can control PHASE, DEPTH or
Rate. After plugging in, the
first knob to be turned is set as
the parameter to be
controlled by the pedal.
After 3 seconds without
turning any knob, the
expression pedal is assigned
to RATE by default.
tremolo / oscillator
The classic tremolo modulates the amplitude of the input audio, while the
harmonic tremolo modulates the audio in two frequency bands, boosting
alternatively low and high frequencies.
Set classic tremolo by pushing the RATE knob, and harmonic tremolo by
pulling the RATE knob.

Save preset
Once the effect is set as desired, press and hold both BYPASS and TEMPO switches simultaneously for 1 second.
The fast blinking of the BYPASS led indicates the “Save preset” mode.
Then, turn the RHYTHM knob to the desired preset number position. Finally, press and hold BYPASS and TEMPO
switches simultaneously for 1 second. Now, the preset has been saved.again

“Save preset” mode can be cancelled, without the saving action. To do this, follow instructions as in “Exit
preset”.
To load a preset, press and hold the BYPASS switch. The fast blinking of the white BYPASS led indicates the
“Load preset” mode.
Without releasing the switch, turn the RHYTHM knob to the desired preset number position, and then release the
BYPASS switch. Now, the preset is loaded and running.

The BYPASS led blinks in a short-long-short-long sequence, which indicates that the device is running a preset.
While running a preset the different knobs and parameters may be changed, which doesn’t change the preset
that is saved in memory.
To stop running the preset, press both BYPASS and TEMPO switches shortly (less than 1 second).
From that time on, the device uses the parameters that are set by the knobs and controls, and stops running
the preset. The BYPASS led stops blinking with the preset sequence.
