TONAL RECALL RKM
INSTRUCTIONS
OVERVIEW
Buckle up, it’s time to go back to Mars. The “Red Knob Mod”
version of Tonal Recall is built around 4 re-issued versions of the
legendary MN3005 bucket-brigade delay chips. It’s maximum delay
time is increased to 1100ms and the unmistakable analog character
of this delay is front and center. Tonal Recall expands upon the
classic vintage sounds associated with analog delays of yesteryear
while bringing modern amenities such as tap tempo, optional bypass
with trails, expression control over any parameter, and the ability to
save presets. Every knob and switch is connected to a little digital
brain while your guitar signal stays 100% analog and never gets
digitally processed. Since the control of the effect is digital, it opens
up unprecedented effects and features that have never been heard
or offered in analog stompboxes.
delay time (max 1100ms) and counterclockwise for
decreased delay time. This control is over-ridden by the
tap tempo switch.
NOTE DIVISION TOGGLE
Controls the tap division for tap tempo in regards to
delay length, with the assumption that the user is tapping
on quarter notes. A dip switch in the back of the pedal
lets you access the divisions in the parenthetical if you
so desire. You can also select tap divisions for ramping
parameters dependent on where the “tap control”
dip switch is set. Note that divisions are 2x slower
for ramping.
REGEN
This controls the amount of repeats on the delay. If set
carefully, it can regenerate seemingly forever, and can also
regenerate into self-oscillating madness. The longer that
a delay is regenerated, it will eventually devolve into a
beautiful, smeary, tape-saturated blur.
DEPTH
This controls the intensity of the pitch modulation on
the repeats.
S / L / B TOGGLE
This controls how many Xvive MN3005 delay chips your
delayed signal will pass through. S stands for “short” (1
MN3005, 20ms to 275ms delay), L stands for “long” (4
MN3005, 80ms to 1100ms delay), and B stands for “both”
which creates more of a blurry, reverb-like wash.
TONE (RAMP)
Simply put, this is a magical knob. When you don’t
have any dip switches assigned for ramping, this knob
functions as low-pass tone lter for the repeats of the
delay. Completely clockwise is slightly brighter than your
average analog delay (still dark), and completely counter-
clockwise is black-out murk oil delay darkness. The pedal
is able to compensate for some of the natural attenuation
that happens as the tone rolls off by boosting the delay
signal according to where the tone is set. In regards to
the ramping functionality, due to the digital control of
this pedal you can set this knob to control any of the ve
parameters individually or simultaneously (mix, rate,
time, regen, depth) and have it either modulate or ramp-
and-hold (rise or fall) via dip switches in the back of the
pedal. Essentially, this knob controls the ramp time in
which this takes place.
MIX
Sets the mix between dry, unaffected signal and the
delay’s repeats. Completely clockwise is 100% wet, full
delay path, and in this scenario the signal will be boosted.
This allows for a better mix when the dry signal is mixed
in. Completely counter-clockwise is 100% dry. With the
knob a little past noon, you get a 50/50 wet/dry mix.
RATE
Sets the rate of the LFO (low frequency oscillator) for
the pitch modulation on the repeats. Clockwise for fast
modulation, counter-clockwise for slow modulation.
TIME
Controls the length of the delay. Clockwise for increased
This device complies with part 15 of the FCC rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired operation.

WAVE SHAPE TOGGLE
This controls the shape of the wave for the pitch
modulation on the repeats. Left for triangle, middle for
sine, and right for square.
BYPASS STOMP
Activates or bypasses the effect. This can be changed to
a momentary bypass via a dip switch in the back of the
pedal if it is desired. This pedal allows for “True Bypass”
via a relay, or buffered bypass with “trails” selectable via
a dip switch in the back of the pedal.
TAP / HOLD STOMP
Sets tap tempo, always honors the last two stomps.
Remember, the longest delay the pedal can achieve is
1100ms, so if you try to make it longer it will just default
to that. If, however, you have eighth note tap divisions
dialed in and you are tapping at 2000ms, the pedal will
process that and set the delay time to 1000ms. If you
hold down this stomp switch the pedal will go into self-
oscillating regeneration “runaway” mode. This is the
same effect as if the regeneration knob is set
completely clockwise.
LOWER TOGGLE
This switch recalls presets. The right position recalls one
preset, the left position recalls a different preset. The
middle position will always reect wherever the knob
positions, toggle positions, and dip switch positions are
currently at. In order to save to the right preset slot, you
hold down the right stomp (bypass) for 3 seconds and
then hold down both stomp switches simultaneously for
another 3 seconds. The LED blinks and your setting is
saved. For the left slot, you do the same thing but hold
the left stomp (tap) rst. If you recall a preset, and move a
knob, you will notice that the LED above the toggle goes
dim. This is to signify that something has changed on the
preset. If you want to save this change in the preset, you
will have to save it again.
IN / OUT
¼” mono input jack.
EXP / CV
¼” TRS jack for expression pedal (parameter selectable
via dip switch in the back of the pedal. Tip goes to wiper.
We recommend Mission expression pedals (EP-1 or EP-
25k). Can also be used to for 0-5V Control Voltage (CV) on
tip – the ring should be left oating in this case. There are
many expression pedals that work with Chase Bliss Audio
products, the Mission stuff just happens to be
what we have here.
TAP / MIDI
¼” TRS jack. This can be used as a tap input or output
with a regular ¼” instrument cable. In addition, it can be
used to interface the pedal with a Chase Bliss Midibox.
Much more information on this in the MIDI manual.
POWER & OTHER INFO
This pedal consumes ~150mA and should
be operated with a standard 2.1mm 9V DC
center negative adapter with current supply capabilities of
200mA or more. If you use a “standard” outlet of 100mA,
the pedal will not function properly. Input impedance of
this device is 1M, and output impedance is less than 5k.
EXP / CV CONTROL
& DIP SWITCHES
The Mix, Rate, Time, Regen, and Depth dip switches in
the left bank allow you to control parameters via ramping
or an Expression Pedal / CV. Whenever you plug a ¼” in
to the EXP / CV jack, the pedal automatically knows that
you will be controlling parameters via expression or CV,
not ramping.
DIRECT CONTROL OF
WAVEFORM WITH EXP / CV
If you have something plugged in to the EXP / CV jack,
but do not have any parameters selected via dip switch,
you are allowed to control the modulation delay manually.
The range of this effect can be limited by the position of
the Depth knob. For a maximum sweep, set the Depth
knob to its full clockwise position.
SETTING EXP / CV RANGE
The range of the expression / CV is controlled by the
parameter knob position and the “sweep” dip switch. For
example, if you wanted an expression pedal to control
the regen parameter from no regeneration to the edge
of self-oscillation, you would make sure the “sweep” dip
switch is in the bottom position and set the regen knob at
the setting just before the pedal starts to generate sounds
on its own. If you need more regeneration you simply turn
the regen knob up slightly. This will increase the maximum
range of the expression pedal. This allows you to control
multiple parameters with an expression pedal, but you can
ne tune the range that you want for each parameter.
UNDERSTANDING THE DIP SWITCHES
When you save a preset, all of this information gets saved.
The parameters in red below correspond to an expression
pedal (if one is plugged in).

A very important thing to remember is that ramping always
gets reset when bypassing. The parameters’ current knob
position control where the parameters ultimately will either
start or stop ramping.
The Mix, Rate, Time, Regen, and Depth dip switches on the
left side simply turn that parameter on or off for ramping or
expression / CV capability.
Mix, Rate, Time, Regen, and Depth
dip switches on the right side control whether or not the
parameters will rise (go clockwise in ramp mode) or fall (go
counterclockwise in ramp mode). It also controls how the
parameters will behave with an expression pedal plugged in.
Bounce: When on (and no expression pedal), parameters will
go back and forth (i.e. modulate), if it’s off, parameters will
ramp and hold.
Trails: This switch allows you to select bypass type. With trails
“off” the bypass is normal, true bypass. With trails in the
“on” position, you have a buffered bypass where the delay
trails spillover into your dry tone. It is important to remember
that with trails mode engaged, if you have the pedal set in a
conguration that is causing self-oscillation, this will not stop
simply because you are in bypass.
MoToByp: Momentary-to-bypass. If on, the pedal is only
activated when the bypass stomp is pressed in.
Tap Control: “R” stands for ramp, “P” for parameter (RPM
in this case). In the P position, tapping in a tempo will
dictate the RPM rate. In the R position, tapping in the tempo
will dictate the Ramp rate. This is great for modulating
parameters. Remember, the “Bounce” dip switch needs to
be on if you want to ramp parameters back and forth, rather
than just ramping and holding.
Tap Division: In position “3” allows for second set of tap
divisions starting with eight note triplet. This is also important
for selecting MIDI note divisions.
Sweep: this controls where ramp sweeps. In “T” (top)
the ramping (or expression control) will occur between the
current knob position and the max position (fully clockwise).
In “B” (bottom) the ramping (or expression control) will occur
between the current knob position and the minimum position
(fully counterclockwise).
NOTE: It may seem overwhelming and difcult
for users to take all this in at rst. My suggestion is always to
forget about the dip switches for a while when you get the
pedal. Get to know the basic functionality of it, and then if/
when you want to experiment with ramping or expression,
it will likely be easier.
Some of these concepts are much easier to explain and
demonstrate on video, and I have many tutorials available on
my youtube channel at
