Mod Machines: Common Parameters
All Mod Machines share a set of parameters. These parameters are saved with each preset and include:
Tap Division: Selects the subdivision to use for LFO speed when tapping in a tempo.
Tap division options include:
Whole, Half, Quarter(default), Dotted Eight, Eighth, Triplets, Sixteenth notes
note: If TAPDIV is set to anything other than Quarter notes, the TAP LED will pulse in amber
Pre / Post: Allows confi guration per preset of the pre/post confi guration available via the rear panel
toggle switch. When Mobius is used in pre/post confi guration, set to “PRE” to place the
modulation effect in front of your amp and set to “POST” to place the modulation effect in
your amp’s effect loop.
Name: Allows editing the 16 character name of the current patch. Use the VALUE encoder to
change the selected character. Use the TYPE encoder to select a character. Exit by pressing
the VALUE encoder, then press and hold the TYPE encoder to SAVE the name permanently.
note: For the patch name to be displayed the NAMES global must be set to ON or SCROLL.
Expression Pedal ON/OFF: Enables or disables the expression pedal input for each patch.
Expression Pedal Set: Enters the expression pedal setup for each patch. All knobs can be confi gured to be
used with the expression pedal. To set up which knobs are controlled by the expression
pedal, push the Value encoder when it displays “EP SET” and it will then display “HEEL”.
Turn the knob(s) to the position desired at heel down on the expression pedal. Then, turn
the Value encoder right to display”TOE” and set the knobs to their desired values at the toe
down position on the expression pedal. An expression pedal can control all of the knobs
simultaneously.

Mod Machines: Chorus
A full featured Chorus with 5 distinct modes. dBucket, Multi and Vibrato all utilize our dBucket variable clock technology for
classic analog bucket brigade style chorusing. dBucket utilizes a single LFO while Multi utilizes multiple LFOs simultaneously
for a distinctly rich sounding chorus. Vibrato is a pitch modulation effect reminiscent of bucket brigade style pitch modulation
effects. The Detune and Digital modes are clean digital chorus effects reminiscent of the rack effects of the ‘80s. Detune
applys a “thickening” effect to your signal while Digital is a crystal clear chorusing algorithm.
PARAMETERS:
Mode: Selects the current Chorus algorithm. Each algorithm is completely unique in its
sonic character.
||||||||
- | +
Mix: Sets the Mix of the wet Chorus signal relative to the uneffected dry signal. A 50/50
mix is usually the most typical setting.
Tone: Allows adjustment of the brightness of the effected signal.
TIPS & TRICKS:
dBCKET mode covers the sounds of the classic analog choruses from the 1970’s. Turn the DEPTH Knob to 12:00 and the
MIX parameter at around 80% for the coveted large-box chorus sound. Turn the MIX back to half-way to experience the
sound of the fi rst compact chorus pedal.
MULTI mode’s three dBucket modulated-delay- lines allow for super-lush modulation at high mix and depth levels
without excessive ‘warble’. If you have a stereo rig, you owe it to yourself to check this out. Try preset 00A for starters.
VIBRTO mode uses our dBucket and variable-clock technology to capture the warmth of old-school stomp circuits. Set
the MIX param to maximum for pure vibrato. Reduce the MIX to add some dry signal to give a vibrato-infl uenced chorus.
DETUNE mode mixes a pitch-detuned signal with the dry input to create a chorus that doesn’t use an LFO. The SPEED
knob controls the pitch shift from -25 cents to +25 cents, while the DEPTH knob adds a widening or doubling effect as it
is turned up for a distinctive ‘80s feel. Set MIX to 50% for the fullest effect.
DIGITL mode uses a classic modulated digital delay line to produce clean, pristine, unadulterated chorus tones. Set MIX
to 50% for traditional digital chorus sounds.

A deep and rich Flanger with a wide pallete of sonic possibilities. Six separate modes cover a variety of fl anger sounds. Each
separate algorithm uses dBucket technology at its heart for authentic recreations of classic bucket brigade fl angers.
PARAMETERS:
|||||||||||
|||||||||||
Regen: Adjusts the amount of feedback in the fl anger’s delay line. Adjust high for more extreme
fl anging sounds.
Manual: Controls the delay time of the fl anger. Higher settings produce higher frequency fl anging
effects and vice versa.
TIPS & TRICKS:
SILVER mode creates textured, airy fl anging. Turn up the Depth and Regen params to add color to stacatto rhythm
parts, or turn back for a mellower chorus-like effect.
GREY mode’s logarithmic LFO creates a dramatic sweep that lingers at the higher registers when the DEPTH knob is
high and the speed is slow. Increase the REGEN parameter to intensify the effect.
BLACK mode’s super-wide sweep creates a signature ‘swoop’ at high depth settings. At fast speeds, this mode will get
crazy.
In the ZERO modes with the MANUAL parameter at minimum, the ‘top’ of the sweep just passes through zero.
Increasing the MANUAL parameter moves the sweep even further past zero. Increase the DEPTH to add lower
frequency fl anging at the ‘bottom’ of the sweep.
- a re-creation of the classic “silver box” fl anger
- the classic “grey box” fl anger featuring its unusual LFO waveshape
- one of the most sought after fl ange sounds in history, with positive regeneration
- the black box fl anger with negative regeneration
- a through zero fl anger with positive regeneration
- a through zero fl anger with negative regeneration

Mod Machines: Rotary
A realistic recreation of a rotary speaker cabinet commonly used with tonewheel organs and guitars. Just like an actual
rotating speaker cabinet, the speed of rotation can be varied between slow and fast speeds.
PARAMETERS:
Horn Level: Controls the output of the high frequency rotating horn driver.
TIPS & TRICKS: In the ROTARY machine, the SPEED knob controls the fast rotor speed. Set the DEPTH control high for
close-miking and maximum intensity, and dial it back for a more mellow effect.

Preamp Drive: Controls the drive of the rotary cabinet’s tube preamp and phase inverter stages.
Turn up for a more overdriven cab sound.

Slow Rotor speed: Controls the speed of the rotors in SLOW speed.

Acceleration: Controls how quickly the rotors transition from Fast to Slow and from Slow to
Fast speed. The rotors will accelerate independently.

speed toggle.
