this button when the DELAY knob controls the delay time will not change the
delay time.
FEEDBACK Knob – Controls the amount of signal that is circulated from the
output of the delay block to its input. Turning the FEEDBACK knob clockwise
increases the number of echoes. Setting the FEEDBACK control to its maximum
clockwise position will cause the DMMTT to run-away, or self-oscillate.
Alternatively setting the FEEDBACK knob to its minimum position will yield just
one echo or repeat for each of your notes. The FEEDBACK knob is also used to
set the maximum amount of feedback for expression pedal control.
DEPTH Knob – Sets the amount of modulation that is applied to the delay time.
As you turn the DEPTH knob clockwise, the amount of modulation increases.
Turn the DEPTH down to the full Counter-Clockwise (CCW) setting to turn
modulation off. The DEPTH knob is also used to set the maximum amount of
modulation for expression pedal control.
RATE Knob – The RATE knob’s main function is to set the rate or speed of
modulation. As you turn the RATE knob clockwise the modulation rate will
increase. The DEPTH knob must be set above the full CCW position to hear the
RATE knob change modulation speed. Additionally the RATE knob sets the
maximum rate of modulation for expression pedal control.
GAIN Knob – Sets the input gain for the DMMTT. As you turn the GAIN knob
clockwise, the input gain will increase. The total gain range is -13 dB to +20 dB.
The gain block is the first stage that the input signal goes through in the circuit.
Both the dry and wet signals mixed by the BLEND knob go through the gain
block.
BLEND Knob – The BLEND knob is a wet/dry control allowing you to vary the
mix between direct and delayed signals at the OUTPUT jack of the DMMTT. Set
the BLEND knob to the full clockwise position for an output that is 100% wet. Set
the Blend knob to full counter-clockwise for an output that is 100% dry. Setting
BLEND anywhere in between will mix the wet and dry signals together.
Additionally the BLEND knob sets the maximum wet/dry mix for expression pedal
control.
SWITCHES & LEDs
BYPASS Footswitch and STATUS LED – The BYPASS FSW is used to toggle
the DMMTT between effect mode and true bypass mode. The red STATUS LED
will light up when in effect mode and turn off in bypass.
EXP. MODE Button and LEDs – The EXP. Mode button cycles through the six
available expression modes: BLEND, RATE, DEPTH, FEEDBACK, DELAY and OFF.
Each time you press the EXP. MODE button the DMMTT will advance to the next
expression mode LED. An expression pedal must be plugged into the EXP. PEDAL
jack to make use of these modes. A lit LED for one of the modes indicates the
