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.
- 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.
- 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.
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.
CHORUS – Green mode is a traditional chorus. Orange mode is a trichorus, 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).
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.
- 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.
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.
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.
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.
– LFO SHAPES & ENVELOPES – Different LFO (low frequency oscillator) shapes dramatically change the feel and sound of a given modulation. In TREM, VIBR, FLANGE, TZF, PHASE, and FILT types, you can adjust the LFO shape with a secondary control (turning the RATE knob when in secondary mode, see page 7). In FLANGE, PHASE, and FILT types, you can also set this “LFO shape” to your playing envelope, where the sound of the effect will be directly related to the volume of the input signal at a given moment.
TZF Shapes – Barber Pole In the TZF (through-zero-flanger) type, the default LFO shape is the sine wave like in all other modulation types. The two other options are what are known as barber poles. These are similar to the rising/falling sawtooth, but instead of a hard reset at the minimum/maximum, the LFO is done in a way where it sounds like it is going in a certain direction forever. ENVELOPES In FLANGE, PHASE, and FILT types, you can set the LFO shape to be a positive or negative envelope.
FLANGE TZF PHASE & FILT – FILTER MATRIX MODE – In FLANGE, TZF, PHASE, and FILT types, you can enter “filter matrix mode” by bringing the RATE knob all the way to minimum. At this point, all modulation will stop, and you can set the exact placement of the “filter” (in the case of FLANGE and TZF, technically delay) with the DEPTH knob.
– SUMMARY CHART – Below is a brief chart showing, for each modulation type, what the VOLUME/COLOR knob controls, the difference between the green, orange, and red modes (more info on page 4), and the secondary controls for the RATE and VOLUME/COLOR knobs (more info on page 7).
