Rhythm
knob selects 1 of 8 different accented
rhythmic patterns to emphasise specific tremolo
pulse beats. The following time signatures are
available: 1/1, 1/2 (march time), 3/4 (waltz time), 4/4
(rock/pop), 5/4 and 6/8 time along with other
patterns. As the ‘Rhythm’ knob is rotated clockwise
the time signature increases producing ever more
complex patterns until the
Delta-Trem
begins to
sound more like a sequencer than a tremolo!
Note: ‘Shape’, ‘Depth’, ‘Speed’ and ‘Rhythm’ knobs
affect the ‘Left’ tremolo. To alter these parameters
the ‘Right’ tremolo press and hold the ‘Tap/Sync’
footswitch whilst adjusting the knobs (with jumper
Link
removed).
Filament/Fluid/Neon
switch selects between three
banks of different L.F .O. waveforms. The ‘Filament’
bank contains subtle triangle, sine and smoothed
square wave shapes; the ‘Fluid’ bank contains rising
saw, triangle and falling saw wave shapes; and the
‘Neon’ bank contains deep pulse wave shapes.
Mono/Stereo
switch allows the
Delta-Trem
to work
as a tremolo/panner/splitter for mono sources (such
as guitar) or as a true stereo tremolo for use with
stereo keyboards. When the switch is ‘up’ the input
is mono (TS) and when ‘down’ it’s stereo (TRS).
Bypass
footswitch allows selection between
‘effectified’ (tube buffered tremolo) and ‘non-
effectified’ (true bypassed ‘dry’) signal.
Tap/Sync
footswitch sets the tremolo speed of the
Delta-Trem
. Two or more successive presses (taps)
of the footswitch set the speed 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
tremolo to the beginning of its cycle allowing
resynchronisation with the beat when playing in a
live situation.
Note: Tremolo 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
Delta-Trem
.
Internal
Dwell
trim-pot sets the bias point of the
filament lamp to alter the depth and character of the
tremolo. To access the ‘Dwell’ trim-pot, first
disconnect the power to the pedal, carefully unscrew
the six screws underneath the pedal and then
remove the base-plate. A small watchmaker’s
screwdriver or specialised trimming tool will be
required to adjust the trim-pot.
TONE TIP! The
Delta-Trem
can be utilised as an
audiophile tube boost/buffer/splitter when the ‘Depth’
knob set to minimum and with the ‘Dwell’ trim-pot
maxed out.
