DELUXE MEMORY BOY
Tap Tempo Analog Delay
Congratulations on your purchase of the Electro-Harmonix Deluxe Memory Boy, a true analog
delay with the ability to tap in the delay time. The Deluxe Memory Boy (DXMB) also includes two
types of delay time modulation, an effects loop in the feedback path of the delay block, an input
gain control, tap tempo divide and optional expression pedal control over four parameters:
Delay Time, Feedback, Modulation Depth and Modulation Rate. The DXMB is true bypass.
-CONTROLS and INDICATORS -
KNOBS
DELAY Knob Sets the delay time from 34 mS to 700 mS. As you turn the DELAY knob
clockwise, the delay time will increase. If you tap in the delay time, using the TAP Footswitch,
the DELAY knob’s setting will be ignored until you move it again. If you turn the DELAY knob
after tapping in a delay time, the DELAY knob’s setting will supersede the last tap tempo that
was entered. Turning the DELAY knob, while listening to your echoes, will bend the pitch of your
notes. The DELAY knob can also be used to set the maximum delay time for expression pedal
control. the TAP DIVIDE button functions have no effect on the DELAY knob; pressing thN.B.: is
button while 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 DXMB to run-
away, or self-oscillate. If instead you only want to hear one echo for each of your notes, turn
the FEEDBACK knob down to its full counter-clockwise position. The FEEDBACK knob is also
used to set the maximum amount of feedback for expression pedal control.
DEPTH Knob Sets the amount of triangle or square wave modulation that is applied to the
delay time. The DEPTH knob has a center detent which signifies the off position for no
modulation. Triangle wave modulation occupies the counter-clockwise half of the DEPTH knob,
square wave modulation the clockwise half of the DEPTH knob. As you turn DEPTH counter-
clockwise from the center-detent’s off position, the amount of TRIANGLE wave modulation
increases, to its maximum setting at full count -clockwise on the DEPTH knob. As you turn the er
DEPTH knob clockwise from the center-detent position, the amount of square wave modulation
applied to the delay time increases, to its maximum setting at full clockwise on the DEPTH knob.
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 to
somewhere other than the off position to hear the RATE change modulation speed. knob
Additionally RATE knob sets the maximum rate of modulation for expression pedal control. the
The DXMB has a low cut tone control feature which the RATE knob adjusts. Enter low cut
mode by pressing and holding down the EXP. MODE button for 2 seconds. After two seconds, all
of the EXP. MODE LEDs will light solid and you can release the button. At this point, the RATE
knob no longer adjusts the rate of modulation but instead sets the frequency for the DXMB’s low
cut filter. As you turn RATE clockwise, less bass will be present in the delayed signal. To
completely bypass the low cut filter so that the full bass response comes through, turn the RATE
knob down to the full counter-clockwise position. To exit low cut mode, press and release the
EXP. MODE button. The DXMB will save the low cut setting, even after power cycling, and it will
remain at that setting until adjusted again. The default setting from the factory is for the low cut
filter to be bypassed.
GAIN Knob Sets the input gain for the DXMB. As you turn the GAIN knob clockwise, the
input gain will increase. The total gain range is -6 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 the by
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 DXMB. 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.
SWITCHES & LEDs
BYPASS Footswitch and STATUS LED The BYPASS FSW is used to toggle the DXMB
between effect mode and true bypass mode. The red STATUS LED will light up when in effect
mode and turn off in bypass.
TAP Footswitch The TAP FSW is used to tap in the delay time. Stomp on the TAP FSW two
times and the delay time will jump to the time between taps (if all the TAP DIVIDE LEDs are
off). If you tap more than twice, it will average the tap tempo for all taps. The DXMB will always
take into account the TAP DIVIDE setting when determining the delay time from the tap tempo.
For example, if your tap time is 1 second and the TAP DIVIDE setting is eighth notes, the actual
delay time is changed to 0.5 seconds. The maximum delay time, when tapped in, is 1.5
seconds; though at this delay time the effect will sound quite - .lo fi The DXMB will save
and recall the tap tempo when power cycling.
N.B.: The delay time for the DXMB is always set by the last method used. If you tap in a delay
time, the DELAY knob’s setting ignored. After tapping in a delay time, if you turn the delay is
knob, the tap time will be forgotten and replaced by the current position of the DELAY knob.
BEAT LED The green BEAT LED always blinks at a rate that reflects the current delay time,
whether you used the TAP FSW or the DELAY knob to set the delay time. The BEAT LED will
also reflect the actual delay time rather than your tap time. For example, if your tap time is 9 00
mS but have the TAPE DIVIDE setting at eighth note triplet, the actual delay time 3 so is 00 mS
the BEAT LED will blink every 3 . If you are modulating the delay time, the change in delay 00 mS
time due to modulation will also be reflected in the BEAT LED.
WARNING:
Your
Deluxe Memory Boy
comes equipped with
an Electro-Harmonix
9.6DC-200BI
power supply
(same as used by Boss & Ibanez 9.6 Volts DC 200mA). The Deluxe Memory Boy ™ ™:
requires 100mA at 9VDC with a plug that is center negative. The DXMB does not take batteries.

the wrong adapter may damage your unit and void the warranty
TAP DIVIDE Button and LEDs This button cycles through the six possible settings for TAP
DIVIDE. Each setting, except when all LEDS are off, will divide the tap tempo create shorter to

the musician taps in a quarter note. That quarter note can then be vided down to five other di
types of notes: dotted eighth note, quarter note triplet, eighth note, eighth note triplet and
sixteenth note. The sixth mode is quarter note or OFF, where the tap tempo is not divided down
and the delay time is set to your actual tap time No LEDs are lit when Tap Divide is set to .
quarter note/OFF. Below is a chart displaying the six available modes and how they divide down
the tap tempo to produce the actual delay time plus an example delay time setting:

N.B. The TAP DIVIDE but has no effect on the delay time when the delay set by the ton is
DELAY knob. Cycling through the different TAP DIVIDE modes, when the delay time was last set
by the DELAY knob, will not change the delay time in any way.
The TAP DIVIDE button setting is saved and recalled when power cycling.
TAP DIVIDE SEQUENCE MODE The DXMB contains a t easter egg called Tap Divide lit le
Sequence mode. In this mode, the DXMB will automatically cycle through the six tap divide
modes at a rate set by the RATE knob. To use this mode, do the following:
1. Tap in a delay time. Tap Divide Sequence mode will not work if the delay time is
set by the DELAY knob.
2. Press and hold the TAP DIVIDE button for 2 seconds. After 2 seconds, all of the
TAP DIVIDE LEDs will light up briefly, now you are in sequencer mode. You can
release the button.
3. Turn the RATE knob to change the speed of the sequence. You should see the
tap divide LEDs light up in a sequential fashion.
4. You can tap in new delay times to change the delay time range.
5. To exit Tap Divide Sequence mode: hold down the TAP DIVIDE button for
another 2 seconds. All 5 LEDs will light briefly to indicate you have exited
sequence mode. You could also simply turn the DELAY knob.
EXP. MODE Button and LEDs The EXP. Mode button cycles through the five available
expression modes: RATE, DEPTH, FEEDBACK, DELAY and OFF. An expression pedal must be
plugged into the EXP. PEDAL jack to make use of these modes. When one of the LEDs of any of
the four modes is lit, the expression pedal will control that parameter. For example, if the RATE
LED is lit, the expression pedal controls the modulation rate, from slowest (expression pedal =
toe up), to the RATE knob’s current setting (expression pedal = toe down). The OFF setting
allows you to disable the expression pedal while it remains plugged into the DXMB. The setting
for the EXP. MODE is saved and recalled when power cycling.
LOW CUT MODE The EXP. MODE button is also used to enter and exit low cut mode. Low
cut mode places a high pass filter after the bucket brigades in the delay section to remove bass
or low frequencies from the delayed signal. To enter low cut mode, press and hold the EXP.
MODE button for 2 seconds. All four Exp. Mode LEDs will light up indicating that you are in low
cut mode. Now you can release the button. Use the RATE knob to adjust the amount of bass
roll-off in the wet signal; as you turn RATE clockwise you will hear less bass. Turning the RATE
knob to full counter-clockwise completely bypasses low cut mode. The factory default setting
bypasses low cut mode. To exit low cut mode, press and release the EXP. MODE button, it will
return you to the previous expression mode setting while saving the new low cut setting. The
low cut mode setting is also saved and recalled when power cycling the DXMB.
LOW CUT MODE BYPASS There are two ways to bypass low cut mode: 1) Enter low cut
mode by holding down the EXP. MODE button, then turn the RATE knob down to the full
counter-clockwise position. 2) While powering up the DXMB, hold down the EXP. MODE button.
It will immediately set the DXMB to bypass the low cut filter and also save the new setting. To
bypass low cut mode, you must press and hold the EXP. MODE button before applying power to
the DXMB.
I/O & POWER JACKS
EXPRESSION PEDAL CONTROL The Deluxe Memory Boy allows external control over four
of its parameters: modulation RATE, modulation DEPTH, FEEDBACK and DELAY time. Please see
the EXP. PEDAL Jack section on the following page for suggestions on the type of expression
pedals to use. The pedal will need to have a TRS plug. You may also use a control voltage
between 0 V and 5 V.
Use the EXP. MODE button to choose the knob you want to control with an expression pedal;
repeatedly press and release the EXP. MODE button until the proper LED lights up. After
selecting a parameter, its associated knob will now set the maximum sweep range, which is the
toe down position for the expression pedal. For example, if you want to sweep the full range of
the FEEDBACK knob, you will need to set the FEEDBACK knob to its full clockwise position. The
expression pedal will then sweep from 0% feedback (toe up position) to 100% feedback (toe
down position).
Some expression pedals allow you to dial in the toe up position using an extra knob on the
pedal itself. When using this type of pedal you can set the range for both toe up (using the knob
on the pedal) and toe down (using the selected knob on the DXMB). If you use an expression
pedal that does not allow you to dial in the toe up position, then toe up will always be that
particular knob’s minimum setting.
The minimum setting for the RATE, FEEDBACK and DELAY knobs is the full counter clockwise
position. The minimum setting for the DEPTH knob is the center detent position at 12 o’clock. In
the case of the DEPTH knob, the expression pedal will always sweep from the 12 o’clock
position (toe up = depth off) to wherever the knob is set (toe down = maximum depth). So the
expression pedal will not sweep through both the Triangle and Square waves, but sweeps
through whichever side you have the DEPTH knob pointed to. For example, set the DEPTH knob
to 3 o’clock, approximately 50% square wave depth, and the expression pedal will sweep from
no depth (toe up) to 50% square wave depth (toe down).
EFFECTS LOOP The Deluxe Memory Boy has an effects loop feature which allows other
effects to be inserted into the feedback loop of the delay block, before the bucket brigade chips.
This means that you can put additional effects on your wet signal without changing your dry
signal and each time your notes go around the feedback loop, they will also go through the
effects loop .
For example, if you connect a Micro POG in the DXMB’s effects loop, set the Micro POG to ting
output only the upper octave, the delayed note will be one octave above the dry note that you
played. Additionally, with a fair amount of feedback on the DXMB, each time the note circles
around the delay loop, the signal will go up another octave. So if you play a C2 on the guitar,
the first echo will be a C3, the second C4, the third C5 and so on.
Another example would be to plug a volume pedal into the DXMB’s effects loop. The volume
pedal will act as a FEEDBACK control. With the addition of an expression pedal, you could have
two pedals controlling parameters on the DXMB.
To properly use the DXMB’s effects loop, connect the SEND jack to the input of your effects loop
and the RETURN jack to the output of your effects loop.
N.B. If you do not wish to use the effects loop, please leave the RETURN jack disconnected.
INPUT Jack Connect the output of your instrument or other effects pedal to the ¼” INPUT
jack. The impedance presented at the INPUT jack is 1 M .
OUTPUT Jack Connect the output of the DXMB to the input of an amplifier or another effects
pedal.
SEND Jack Connect this jack to the input of another effects pedal or chain of effects pedals.
RETURN Jack Connect this jack to the output of another effects pedal or chain of effects
pedals. The input impedance presented at the RETURN jack is 2 M .
EXP. PEDAL Jack Allows the musician to control any of the four available expression modes
with an optional expression pedal or control voltage. The expression pedal should have a Tip-
Ring-Sleeve plug attached to it. It is important that the expression pedal have the correct
polarity. The tip of the plug must be connected to the wiper of the potentiometer inside the
expression pedal. If you are not sure what type of expression pedal to use, try to purchase one
with a polarity switch so that it will work with many different types of instruments. Some
suggested Expression Pedals: M-Audio EX-P, Moog EP-2, Roland EV-5 or Boss -500L. You may FV
also connect a control voltage to this jack. The Control Voltage range must be 0 V to 5 V.
9V PWR JACK Connect the output plug of the supplied AC Adaptor into the 9V power jack at
the top of the MB. The DX DXMB’s current requirement is 0mA at 9VDC. The polarity of the 10
power jack is center negative. The maximum allowable power supply voltage is 12 VDC.
