Blend
knob adjusts the mix of 'dry' and phase-
shifted signals–fully counter-clockwise is 100% 'dry'
signal and fully clockwise is 100% phase-shifted
signal (i.e. true vibrato). When the ‘Blend’ knob is set
centrally at 12 o'clock the mix of 'dry' and phase-
shifted signals is equal, producing a deep, rich
phasing effect. The notch-depth and thus the
intensity of the phasing can be fine-tuned by
adjustment around the centre position.
Note: ‘Shape’, ‘Width’ and ‘Speed’ knobs affect LFO

. To alter these parameters for LFO

press and
hold down the ‘Tap/Sync’ footswitch whilst adjusting
the knobs (with jumper

Colour
toggle switch introduces two different types
of resonance (feedback). With the switch set ‘down’
feedback is routed from the 4
th
phase-shift stage.
This works well with acoustic guitar at slower sweep
rates adding movement and texture. When the
switch set ‘up’ feedback is routed from the 2
nd
phase-shift stage, which is subtler . Note: because of
how the feedback is injected back into the phase-
shift stages the action of the ‘Blend’ knob is
reversed. When the switch set in the ‘centre’ position
no feedback is introduced.
Bypass
footswitch allows selection between
‘effectified’ (tube buffered phasing) and ‘non-
effectified’ (true bypassed ‘dry’) signal.

Normal/Skewed/Scattered
toggle switch selects
between three banks of different LFO waveforms.
The ‘Normal’ bank contains symmetrical linear
sweep waveforms; the ‘Skewed’ bank contains a
range of lopsided waveforms; and the ‘Scattered’
bank contains harder transition, stepped and pulse
waveforms.
Tap/Sync
footswitch sets the rate of sweep. Two or
more successive presses (taps) of the footswitch set
the rate according to the foot tap rate putting the
pedal into ‘tap tempo’ mode. Moving the ‘Speed’
knob slightly will put the pedal back into ‘standard’
mode. One press just resets the phase sweep to the
beginning of its cycle allowing resynchronisation with
the beat when playing in a live situation.
Note: Phase sweep speed can also be set
accurately using an external tap tempo controller
such as the
Time Traveler™
pedal or any controller
pedal that features a normally open momentary
footswitch. Connection is made via the RCA jack
socket on the rear panel of the
Phaseomatic
.
Internal
Feedback
trim-pot sets the amount of signal
fed back from the phase-shift stages to create
resonance and self-oscillation effects–beware of
high output levels! To access the ‘Feedback’ trim-
pot, first disconnect the power to the pedal, unscrew
the six screws underneath the pedal and remove the
base-plate. A watchmaker’s screwdriver or trimming
tool will be required to adjust the trim-pot.
