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

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

tempo enable/disable setting until it is changed again, even if the pedal is

removed from power.

You can also reset the internal footswitch’s tap tempo to the factory

default setting of enabled by holding the footswitch when resetting

secondary knob settings. See step 3 in “Erasing Secondary Knob Settings”

on page 8.

ROTARY SPEED SWITCH

There is no tap tempo available for the ROTARY mod type. When an

external switch is connected to the TAP IN jack, clicking that switch will

accelerate/decelerate the rotation speed. The “fast” speed is the default

speed, set with the RATE knob. The “slow” speed is set by a secondary

knob control (see page 9). The external acceleration switch only works in

the ROTARY’s green mode.

MOMENTARY

If you are in bypass mode and you press and hold down the footswitch,

you will now be in momentary mode and the MOD 11 will re-enter bypass

upon releasing the footswitch. You can disable this option by unscrewing

the back plate of the MOD 11 and switching the internal “TAILS” switch to

off. This option is good for adding quick accenting effects on only certain

moments of your playing.

- SECONDARY KNOB FUNCTIONALITY -

The MOD 11 allows you to take even more control over each modulation

by accessing “hidden” parameters through Secondary Knob Mode. Use the

secondary knob parameters to fine tune the exact tone you want, or push

the MOD 11 into wild, unexpected sonic territory.

Within a certain modulation type, unless otherwise specified, all secondary

controls are global between the two to three modes (green/orange/red)

of that modulation type. Unless otherwise noted, changing a secondary

control in a modulation’s green mode will also change it in its orange/red

mode, if applicable.

USING SECONDARY KNOB MODE

1. Turn the MODULATION TYPE knob to the modulation you would like

to edit. Secondary knob functions are available for every type.

2. Press and hold the MODE button for 1 second. The LED will blink in

an on-on-off pattern to indicate that the MOD 11 is now in Secondary

Knob Mode.

3. Turn the RATE or VOLUME/COLOR knobs to edit the secondary knob

function for that modulation type and its selected mode.

4. To exit Secondary Knob Mode, press and release the MODE button.

The LED will stop blinking. The modulation time and tone set by the

RATE and VOLUME/COLOR knobs before entering Secondary Knob

Mode are preserved until you repeat this process again to change

them or you erase/reset secondary knob parameters.

USING OTHER CONTROLS IN SECONDARY KNOB MODE

1. The DEPTH and MODULATION TYPE knobs always function normally

in Secondary Knob Mode.

2. When using the RATE or VOLUME/COLOR knob to set a secondary

knob function, the modulation rate and volume/color that was set by

those knobs before entering Secondary Knob Mode are preserved.

3. The footswitch functions normally in Secondary Knob Mode. If the

footswitch is used to put the MOD 11 in bypass mode, Secondary Knob

Mode will remain active, and moving the knobs will change their

secondary knob parameters. The LED will blink in a shorter version of

the Secondary Knob Mode pattern. If tap tempo mode is enabled, you

can use the footswitch to tap in a new modulation speed as usual.

4. Secondary knob settings are preserved when switching away from a

particular modulation type and are preserved when power cycling the

MOD 11. When secondary knob functions are set in one modulation

type, they do not affect the secondary knob functions of another

modulation type.

ERASING SECONDARY KNOB SETTINGS

1. To erase the secondary knob settings of a particular modulation type,

press and hold the MODE button. Then, while holding MODE, press

and hold the footswitch for 2 seconds. The LED will blink quickly

indicating that the secondary knob settings of the current modulation

have been reset to the default factory settings.

2. To erase the secondary knob settings of every type and restore them

all to factory defaults, first unplug the MOD 11 from power. Press and

hold the MODE button. Then, while holding MODE, plug power back

in to the MOD 11. The LED will blink quickly, indicating that all

secondary knob functions have been restored to the factory default.

3. To erase the secondary knob settings of every modulation and reset

the tap tempo functionalities of the internal footswitch to the factory

default, first unplug the MOD 11 from power. Press and hold both the

MODE button and the footswitch. Then, while holding both, plug

power back in to the MOD 11. The LED will cycle through red, orange

and green to indicate that the MOD 11 has been restored to factory

default secondary knob settings, mode settings, and tap tempo

settings.

COMMON SECONDARY KNOB FUCTIONS

Many of the different modulation types have similar secondary controls:

LFO SHAPE:

TREM, VIBR, FLANGE TZF, PHASE, PITCH (green mode only)

and FILT all have a secondary control to adjust the LFO Shape. This

function is assigned to the RATE knob when in secondary knob mode. For

more info on LFO Shapes, see page 11.

ENVELOPE FACTOR:

TREM, HARM, VIBR, and ROTARY all have this

secondary control. This only makes a difference when in the orange or red

mode for one of these modulation types. This function is assigned to the

VOLUME/COLOR knob when in secondary knob mode. At maximum (the

default setting for all but VIBR), the envelope has its maximum effect,

playing hard will have maximum rate/depth (depending on what mode

you’re in) and soft playing will have close to zero rate/depth. As you bring

the knob down, this difference is lessened. At 50% the envelope has no

effect. As you bring it below 50%, the effect is flipped, where hard playing

results in minimum rate/depth and softer playing results in maximum

rate/depth (minimum is the default in VIBR).

MIX:

CHORUS, FLANGE, TZF, PHASE, PITCH, and FILT all have a mix

control, assigned to the VOLUME/COLOR knob when in secondary knob

mode. At maximum (the default setting for all but PITCH) you hear the

classic effect. As you bring the mix down, more dry signal is added to the

signal and the effect becomes more subtle. At minimum you will hear just

your dry signal. In the TZF type this doesn’t work when using a barber-

pole shape (see page 12)

OVERDRIVE:

UNI and ROTARY have an overdrive control, assigned to the

RATE knob in secondary knob mode. By default there is no overdrive, bring

this control up to add more overdrive. The exact sound/performance of

this will depend on the level of your input signal.

CROSSOVER:

In the HARM type, this sets the crossover frequency

between the high frequency and low frequency bands that are being

modulated between. By default it’s set towards the center of the knob,

about 550Hz.

SLOW SPEED:

In the ROTARY type, in orange mode the VOLUME/COLOR

knob sets the Envelope Factor (see page 8), but in green mode it sets the

“slow speed.” When using an external switch plugged into the TAP IN jack

in this modulation type, tapping on the footswitch accelerates/decelerates

between fast and slow modulation speeds. The fast speed is the default,

set by the RATE knob. In secondary knob mode the VOLUME/COLOR knob

sets the slow speed as a ratio. At maximum, it’s a 1:1 ratio and the slow

speed will be the same at the fast speed. At 50% the slow speed is half

the speed of the fast speed. At minimum the slow speed won’t be

modulating at all.

SCALES:

In the PITCH type, in orange mode the pitch modulation is locked

to specific note intervals. By default it’s chromatic, but this “scales” control

can set it to different pitch intervals. The other options are whole tone

scale, octaves, octaves & fifths, major arpeggio, and minor arpeggio. The

nature of the LFO and different pitch intervals can lead to some wacky

rhythmic effects. In secondary control mode, the RATE knob sets this

effect, based on divisions shown below:
