OVERVIEW: Forget everything you know about analog delay, this one’s different. Built around a pair of re-issued
versions of the legendary MN3005 bucket-brigade delay chips, the unmistakable analog character of this delay is
front and center, along with a velvety tape-like saturation that reveals itself dynamically on a lower input signal
and more and more as the repeats regenerate. 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. Due to the digital control of the pedal,
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.
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 filter 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 five 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 roughly 75% clockwise, you get a 50/50 wet/dry
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 delay time (max 550ms) 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. The saturation is introduced dynamically based on input level, so will
reveal itself more and more with a softer input.
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” (2 MN3005, 40ms to 550ms delay), and B
stands for “both” which creates more of a blurry, reverb-like wash.
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 550ms, 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 1000ms, the pedal will process that and set the delay time to 500ms.
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 reflect 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) first. 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: ¼” mono input jack.
OUT: ¼” mono output 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 floating 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 an Empress Effects 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.
Expression / 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 Expression / 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 Expression / 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 fine tune the range that you want for each
This page has a diagram and explanation of all the dip switches. When you save a preset, all of this information
gets saved. The parameters in red below correspond to the ramp function *or* an expression pedal (if one is
plugged in).
configuration that is causing self-oscillation, this will
Understanding the DIP Switches:
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.
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
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 difficult for
users to take all this in at first. 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 I also love to
hear from customers and answer questions so feel

MIDI Configuration
Tonal Recall allows all of its parameters to be controlled via control change messages, it's presets to be saved and
recalled with program change messages, and its tempo controlled with MIDI clock messages.
To use MIDI with your Tonal Recall, you'll have to do the following:
1) Attach a Chase Bliss Audio Modified Empress Midibox “Ring Active” port using a standard ¼” TRS patch
cable to the TAP/MIDI jack on your Tonal Recall. The Midibox is not included with the Tonal Recall. If you
do not have a modified Empress Midibox, but a standard one from Empress, you need to use a custom TRS
cable that flips the tip and the ring. See to purchase these items.
2) Tonal Recall is set to MIDI channel 2 by default, but it is easy to change if you need to. If you want to change
it, simply hold down both stomp switches when you provide power to the pedal (hold down TAP and
BYPASS switches simultaneously) and then you can let go. The pedal is now looking for the first “Program
Change” message it sees, and it will set itself to whatever channel it gets that first message from,
permanently (until you change it again, of course).
Recalling a preset via MIDI
You can activate a preset by sending a MIDI Program Change message. For example, sending a Program Change
message of 1 activates preset 1. There are 122 total preset slots available. Slots 1 and 2 are the presets that can be
saved and activated directly from the pedal via the preset toggle. Slot 1 is the right slot. Slot 2 is the left slot.
Sending a Program Change message of 0 puts the pedal in “Live” mode which is identical to when the preset toggle
switch is in the middle position, in normal pedal operation. If you do not save something into presets 3 through
122, nothing will be recalled. There are no factory presets besides the two that come loaded in slots 1 and 2. The
idea is for you to create your own.
Saving a preset via MIDI
You save a preset by sending a MIDI Program Change message while holding down both the TAP and BYPASS
stomp switches. For example, sending a Program Change message of 45 while holding down both the TAP and
BYPASS stomp switches will save your current settings to preset 45. There are 122 total slots. Slots 1 and 2 are
the presets that can be saved and activated directly from the pedal via the preset toggle. Slot 1 is the right slot. Slot
2 is the left slot.
MIDI Clock (aka MIDI Beat Clock)
Tonal Recall will respond to MIDI Clock messages. MIDI Clock specifies quarter notes, subdivided into 24 MIDI
Messages. By using the tap selection toggle, you can select different types of notes divisions including quarter note,
dotted eighth note, eighth note, eighth note triplet, eighth note sextolet, and sixteenth note.
Control Change Messages
Tonal Recall can be controlled with MIDI control change messages. Below is a table that shows which MIDI control
change channel controls each Tonal Recall parameter.

Sending value 0 sets divisions for quarter notes, 1 for
dotted eighth notes, 2 for eighth note triplet, 3 for
eighth notes, 4 for eighth note sextolet, and 5 for
sixteenth notes.
Sending a value of 0 causes the pedal to ignore MIDI
Clock messages. Sending a value of 127 causes the pedal
to listen for MIDI Clock
messages. (by default, the pedal listens for MIDI Clock
You can send any value with this CC#, it will simulate
pressing down the tap switch. In short, it’s a way to set
tap tempo via midi.
Sending a value 0 would be equivalent to an expression
pedal being completely “off”, sending 127 is equivalent
to a fully depressed expression pedal. All numbers in
between correspond to knob positions in between those
extremes. As always, the dip switches on the pedal
select which parameter(s) are being controlled via
Sending a value of 127 engages the pedal, sending a
value of 0 bypasses the pedal. Furthermore, sending a
value of 127 with the pedal already engaged will reset
