MOD 11

Multifunction Digital Modulation

Congratulations on your purchase of the Electro-Harmonix MOD 11, the
compact digital modulation pedal that does it all. From classic modulation
sounds to retro-inspired simulations, the MOD 11 features eleven distinct
modulation effects. The MOD 11 is designed to be simple to use for those
looking for fast, plug-and-play ability, but it also features deeper
functionality for players who want more control over their modulation
effects. Tap tempo, multiple LFO shapes, envelope controls, and
momentary mode are just a few examples of deeper options available on
the MOD 11. From simple, subtle warbles to out-of-this-world special
effects, the MOD 11 has got all of your modulation needs covered.

- DESCRIPTIONS OF MODULATION TYPES -

TREM – A classic tremolo effect, modulating the volume of your guitar.

Extra functionality includes multiple LFO shapes plus envelope controls.

HARM – Harmonic tremolo, a lush tremolo effect found in some vintage
tube amps. Your signal is split into high and low frequency bands and
modulated between the two bands. Envelope controls available.

VIBR – A classic vibrato effect, modulating the pitch of your guitar. Extra
functionality includes multiple LFO shapes plus envelope controls.

UNI – A simulation of the swooshing Univibe® effect. A bank of

modulating filters, sounds a bit like a chorus and a bit like a phaser, but
has a character all its own. Includes “chorus” and “vibrato” modes and
added overdrive.

CHORUS – A classic warbling, doubling chorus effect like the EHX Small
Clone. Extra modes include a tri-chorus effect and a bass chorus effect.

ROTARY – A simulation of a rotary speaker cabinet. Extra functionality
includes added overdrive, plus envelope control over the rotation speed.

FLANGE – A classic swooping flanger effect, a modulated delay signal
mixed with the dry signal. Modes for both additive and subtractive flanger.
Multiple LFO shapes available, including envelope following flanger.

TZF – Through Zero Flanger, a flanger effect that crosses through the
“zero point” of the sweep, where the modulated delayed signal meets back

up with the dry signal. Modes for both additive and subtractive flanger,
plus barber-pole flanger options.

PHASE – A classic phaser effect like the EHX Small Stone. Choose from
4, 6, or 8 stage phaser. Multiple LFO shapes available, including envelope
following phaser.

PITCH – A modulated pitch shifter. Chose your main pitch shift (using the
VOLUME/COLOR knob) and modulate around that pitch. Extra functionality
includes a dry blend and stepped pitch modes.

FILT – Modulated filter effect, like those often used on classic analog
synthesizers. Choose between Low Pass, High Pass, and Band Pass filters.
Multiple LFO shapes available, including envelope triggered filter.

- CONNECTIONS -

INPUT Jack – This ¼” jack is the audio input of the MOD 11. The input

impedance is 1M.

OUTPUT Jack – This ¼” jack is the audio output of the MOD 11. The
output impedance is 680.

TAP IN Jack – Connect an external momentary footswitch to this ¼” jack
to control the modulation speed by tapping in a tempo. The external
switch should be normally open. Upon engaging the switch, it should
create a short circuit between the Tip and Sleeve of the plug. For the
Rotary effect tapping this switch once changes the speed of the rotation.

9V Power Jack – Plug the output of the MOD 11’s supplied EHX 9.6DC
200mA AC adapter in the 9V power jack located at the top of the pedal.
The MOD 11 requires 150mA at 9VDC with a center-negative plug.

- CONTROLS -

DEPTH Knob – The exact use of this knob depends on the modulation

type you are using. For most effects it sets the depth or intensity of the
effect. For the Rotary effect it sets the balance between the rotating drum
and horn signals.

RATE Knob – Sets the modulation speed. In some mod types, turning
this knob to minimum enters Filter Matrix Mode (see page 13).

VOLUME / COLOR Knob – For the first six modulation effects, this is
simply a volume knob. For the last five it has a different use. For FLANGE,
TZF, and PHASE it sets the amount of feedback, which increases the
resonance and emphasis of the effect. For PITCH it sets the center pitch
shift that the modulation happens around. For FILT, it sets the resonance.

Modulation Type Knob – This knob is an 11-position rotary switch that
selects which of the MOD 11's modulation types is active.

MODE Button – This button cycles through the available modes of the
active modulation type. Each modulation type two or three modes which
modify the behavior of the active modulation type. See “Mode Button
Functionality on page 4 for more details.

LED – The LED lights when the MOD 11 effect is active and shuts off when
in bypass mode. Its color and blinking pattern also indicate information
about the modulation mode, and tap tempo. See “Mode Button
Functionality” below, and “Footswitch Functionality” on page 5.

Footswitch – Press the footswitch to toggle the pedal between buffered
bypass and effect modes. When the pedal is in effect mode, the LED will
be lit. In most modulations, the footswitch can also be used for tap tempo
by tapping in quarter notes with the switch. See “Footswitch Functionality”
on page 5 for more information.

- MODE BUTTON FUNCTIONALITY -

Each modulation type on the MOD 11 has up to three unique modes of
operation. Pressing the MODE button cycles through these available
modes. The LED color – green, orange, or red – shows the current mode.
Not all modulation types have three modes. When you switch modulation
types, the MOD 11 will recall the last mode you were using in that
modulation type. Below is a description of the available modes in each
modulation type. See the chart on page 14 for a summary of these
descriptions.

TREM – The 3 modes have to do with envelope controls. In green mode
your envelope doesn’t affect anything. In orange mode it affects the rate

of modulation, by default the harder you play the faster the modulation
will occur. In red mode your envelope affects the depth of the effect, by
default the harder you play the more intense the effect is. Exactly how
these envelopes work can be changed using secondary controls, see page

7.

HARM – The 3 modes work exactly as they do in the TREM type.

VIBR – The 3 modes work exactly as they do in the TREM and HARM

types, except the default envelope setting if flipped (softer playing = faster
/ more intense effect).

UNI – There are 2 modes, “chorus” and “vibrato” (as you’d see on a classic

Univibe®). In “chorus” mode (green) the modulated signal is mixed with

your dry signal to create the swooshing effect. In “vibrato” (orange) mode
you hear just the modulated sound, which creates a unique pitch
modulation effect.

CHORUS – Green mode is a traditional chorus. Orange mode is a tri-
chorus, three different modulations occurring at once. Red mode is a bass
chorus, in this mode low end is filtered out of the modulated signal and is
boosted in the dry signal, creating a similar effect as the x-over on the
EHX Bass Clone.

ROTARY – There are two modes, regular (green) and envelope (orange).
The envelope works exactly like the orange mode in the TREM and HARM
types

FLANGE – There are two modes, additive (green) and subtractive
(orange) flanger. The additive is a more traditional flanger sound, while
the subtractive has a more tubular and vocal sound.

TZF – The modes work identically to how they do in FLANGE mode,
additive (green) and subtractive (orange).

PHASE – There are three modes, for the number of phase stages in the
phaser algorithm. 4 (green), 6 (orange), and 8 (red). More phase stages
creates a more intense phaser effect.

PITCH – There are 2 modes, in the green mode the pitch modulation is
smooth. In the orange mode the pitch modulates in fixed pitch steps.

FILT – There are three modes, Low Pass Filter (green), High Pass Filter
(orange), and Band Pass Filter (red).

- FOOTSWITCH FUNCTIONALITY -

TAP TEMPO

For most modulation types, the quarter-note modulation speed can be set
with tap tempo. You can use either the built-in footswitch or an external
tap tempo switch connected to the TAP IN jack. Plugging in an external

footswitch, however, always disables the internal footswitch’s tap tempo

functionality. Tap twice at your desired quarter-note tempo to lock in your
tap time.

You can disable the internal footswitch’s tap tempo function. To

disable/enable internal tap tempo, unplug power from the MOD 11, press
and hold the footswitch, then plug power back in while holding the
footswitch. The LED will slowly blink five times if tap tempo is turned off
or will blink twice if tap tempo is turned on. The MOD 11 saves your tap
