1I N T R O D U C T I O N
Thank you for purchasing the Vibe Machine V-2 pedal from DryBell, Croatia. This is the Options manual. This user’s
manual is for users who want to experiment and play with secondary options that are built into the Vibe Machine V-2. But
if you have purchased the V-2 pedal, you don’t have to change anything if you don’t want to.
For the last five years we have collected feedback from our respected customers and developed these unique
additional features for the Vibe Machine product series, we wanted the Vibe Machine to have a wider set of useful options
to meet the requests put forward by customers. So, we hope that you will find some of these features useful for your
specific needs and also for your pedalboard system. It is important to note that you only need to set the pedal the way you
want it once and it will keep your preferred settings. The pedal can be reset to factory settings at any time very easily using
this simple step: just press the footswitch once, release it and then move the CHORUS/VIBRATO switch up and down
several times. We have provided short instructional videos for most of these features on our YouTube channel ( ).
2WHAT CAN WE DO WITH ADDITIONAL OPTIONS
EMBEDED IN THE VIBE MACHINE V-2?
✓The Vibe Machine V-2 has Cancel mode, Tap Tempo mode, Two speed mode and Fast/Slow Leslie®mode with
adjustable Leslie ramp delay.
✓You can use almost any type of expression pedal (Linear taper, Volume pedal taper, HotPotz II (I) taper, ICAR
taper and more) for external speed control, or you can control speed with control voltage 0-5V (CV).
✓With an expression pedal connected, you can also put the V-2 pedal in Cancel mode or you can use expression
pedal for Tap Tempo mode, rocking the pedal to set the speed.
✓Users that have a Mission Engineering EP-100K expression pedal that they used with earlier versions of the
Vibe Machine V-1 can use it normally for the V-2 too.
✓Instead of an expression pedal you can use an external footswitch for controlling the Fast/Slow Leslie®mode,
Two speed mode, Tap Tempo mode or Cancel mode.
✓For Tap Tempo you can select various multipliers.
✓You can still adjust speed with the regular speed potentiometer mounted on the top of the pedal while the
expression pedal is connected.
✓The V-2 has two types of Cancel mode: original Uni-Vibe® Cancel where the input guitar signal is colored and
slightly boosted, or Vibe Machine Cancel where the cancel tone is colored in the same way but un-boosted.
✓You can enable or disable the Cancel function when using an expression pedal, so, if you want you can use
your expression pedal without the Cancel function.
✓You can fine tune your expression pedal’s taper with 3 different curves, or if needed you can calibrate the
expression pedal's speed range.
✓You can invert the direction of the expression pedal and/or select the Cancel activate position (heel down or
toe down).
✓You can use latching or a momentary type of external footswitch.
✓You can switch off the incandescent light bulb when the pedal is in bypass and extend light bulb life. In this
case, when you turn the pedal on again, it will take about 2 seconds until opto-system reaches its nominal
dynamic working state.
✓If you don’t want the system LED to blink constantly, it can be turned off when the pedal is in bypass.
✓Max speed is adjustable. You can enable the speed limit function for your expression pedal or the regular
speed pot separately.
✓The V-2 pedal can check if the power supply being used is producing suitable power for the pedal, even if other
pedals are connected to the same daisy chain power line.
✓You can reset all these functions and modes to our default FACTORY settings using a one second step.

3SPEED POTENTIOMETER MARKS
Ok, let’s get started! . In the pedal’s normal operation mode when nothing is connected to the PEDAL+ expression
jack the Speed potentiometer will only adjust speed. The Speed potentiometer has setting labels marked around it; E1,E2,
E3, S4, S5, S6, X7, T8, T9 and T10. All positions are utility positions but only positions T8, T9 and T10 (used for Tap Tempo
multipliers) can be changed on the fly while using an external footswitch or expression pedal.
All positions E1, E2, E3, S4, S5, S6, X7, T8, T9, T10 are general utility positions for setting the 'set and forget'
parameters of the V-2 pedal, using two available utility modes: PEDAL+ mode and general SETUP mode, which will be
described later.
The name of each position is pretty logical. Epositions are for setting the Expression pedal modes, Spositions are for
setting external Switch (footswitch) modes and Tpositions are for choosing Tap Tempo multipliers on the fly. X7 is the
position used for utility modes and for maximum speed settings (or Leslie delay) when the pedal is operated in E2, E3 or S5
mode.

4PEDAL+ JACK MODE AND SETUP MODE FUNCTIONS
The Vibe Machine V-2 has two different types of utility modes: the PEDAL+ jack modes (Page 5) and general SETUP
modes (Page 8). All these modes, described in detail later in this manual, are 'set and forget' features of the Vibe Machine
V-2.
When the user selects the PEDAL+ jack mode, the user defines whether an expression pedal or external footswitch is
connected to the PEDAL+ expression jack, and for which features this connected hardware will be used (external speed
control, Cancel mode, Tap Tempo mode, Fast/slow mode or Two speed mode).
With SETUP modes (Table 2, Page 9) the user defines additional secondary settings and features embedded into the
V-2 hardware/firmware structure.
When we developed these modes we also embedded a Reset to Default Factory Settings Function (Page 12) into the
V-2 system. This function resets all V-2 firmware settings to our factory settings, which we are pretty sure are the best
combination of settings for most guitarists and pedalboard builders.

5PEDAL+ JACK MODE
An external expression pedal or footswitch can be connected to the expression PEDAL+ jack to control speed or other
secondary features. PEDAL+ jack features 6 different modes: 3 for expression pedal (E1, E2 and E3) and 3 for external
footswitch (S4, S5 and S6). These are modes used to define the type of hardware that is plugged into the PEDAL+ jack, and
its function. As mentioned before, these are set and forget modes.

5.1 HOW TO SET THE PEDAL+ MODE?
So, if you look at the silkscreen around the speed knob on the V-2 pedal (Figure 1), you can see the settings E1, E2, E3,
S4, S5 and S6 marked around it. To choose a mode using the PEDAL+ jack you need to:
1. Set the speed pot to the wanted position (Settings E1, E2, E3, S4, S5 and S6 around the pot) depending on the
PEDAL+ mode/function that you want to activate. We recommend you to align the white mark on the speed
knob with your chosen setting mark.
2. Using the jack from your expression pedal or footswitch, plug it in and out of the expression pedal socket 3 times
within 3 seconds.
The chosen mode is activated when the system LED lights up orange (it stays orange for 2 seconds). After that 2
seconds the system LED starts blinking green again, activation of your chosen mode is now complete. Once this procedure
is over the pedal continues to work in your selected PEDAL+ mode (of course only if you have something plugged into the
PEDAL+ jack). If nothing is plugged into the PEDAL+ jack the SPEED pot will control speed normally.
After unplugging the power supply the V-2 keeps the PEDAL+ mode you have stored in its internal memory, so there is
no need to repeat the procedure next time the pedal is used. The PEDAL+ connector needs to be plugged in and out 3
times only when you plan to switch to a different PEDAL+ mode or change hardware (for example using a footswitch
instead of an expression pedal or vice versa). So, this is a one time procedure for most users (for example, the user selects
their preferred mode from the PEDAL+ jack options and then mounts the pedal on their pedalboard).
Resetting the pedal to default factory function will set PEDAL+ mode to E1. The following sections will explain what
each of the PEDAL+ modes is used for and how they work.
5.2 PEDAL+ MODE E1
E1 mode for expression pedals is for those who don’t need the Tap Tempo feature, and who want to use both
expression pedal and the pedal’s speed pot to control the speed. Using the speed pot automatically deactivates the
expression pedal’s position/speed setting and vice versa. This is useful in case you want to play a song with a fixed speed
setting. You can use the pedal’s speed pot to set the desired speed easily. Also, the speed pot can be used to
engage/disengage the CANCEL function, or to set a desired Leslie ramp delay.
Turning the SPEED pot changes the speed of pulsations (full speed range from MIN to MAX)
✓Moving the expression pedal automatically changes the speed, but at the same time the speed pot position
defines the Leslie ramp delay. If you don’t want to use Leslie ramp function, just set the speed pot on MIN
Swivelling the speed pot back and forth engages/disengages the CANCEL function when the expression pedal’s
heel is down (4 quick ¼ turns of the Speed knob, left-right swivels). When Cancel function is engaged (by
swivelling speed pot) and active (heel down by default) the system LED will be red. See CANCEL types and options
in SETUP MENU (Table 2, Page 9).
No tap tempo

5.3 PEDAL+ MODE E2
E2 mode for expression pedal is for those who only use an expression pedal and don’t intend to control speed with
the pedal’s speed potentiometer. The expression pedal can be used for Tap Tempo and/or to activate the CANCEL function
(heel down by default). The Speed pot is used to set the Leslie ramp delay, engage/disengage CANCEL function (swivelling)
and to set tap tempo multipliers on Speed pot positions T8, T9 and T10.
Turning the SPEED pot from MIN to X7 changes Leslie ramp delay from 0 to MAX delay time. The whole of X7’s
field features the max delay time, meaning you can leave the speed pot’s white tag set anywhere in that field.
If the user sets the SPEED pot to T8, T9 or T10 then the expression pedal works in tap tempo mode, to define
tempo, you have to press the expression pedal fully toe down at least twice or more.
oT8 -> multiplier = x1, system LED flashes red in current tempo
oT9 -> multiplier = x2, system LED flashes green in current tempo
oT10 -> multiplier = CUSTOM (default factory multiplier value = x3), system LED flashes red in current
tempo. You can select custom multiplier in SETUP mode 7 (Table 2, Page 10).
Swivelling the speed pot back and forth engages/disengages the CANCEL function when the expression pedal’s
heel is down (4 quick ¼ turns of the Speed knob, left-right swivels). When Cancel function is engaged (by
swivelling speed pot) and active (heel down by default) the system LED will be red. See CANCEL types and options
in SETUP MENU table 2 (Table 2, Page 9)
5.4 PEDAL+ MODE E3
E3 mode for expression pedal is for those who want to use all available features and automatic switching activity
from speed pot to expression pedal. PEDAL+ mode E3 is a combination of modes E1 and E2.
Turning the SPEED pot changes speed of pulsations (full speed range from MIN to MAX, system LED flashing
green).
If an expression pedal is currently active, turning the SPEED pot from tag MIN to X7 changes the Leslie ramp delay
time from 0 to MAX delay. The whole of X7’s field features the max delay time, meaning you can leave the speed
pot’s white tag set anywhere in that field.
If the user sets the SPEED pot to T8, T9 or T10 then the expression pedal works in tap tempo mode, to define
tempo, you have to press the expression pedal fully toe down at least twice or more.
oT8 -> multiplier = x1, system LED flashes red in current tempo
oT9 -> multiplier = x2, system LED flashes green in current tempo
oT10 -> multiplier = CUSTOM (default factory multiplier value = x3), system LED flashes red in current
tempo. You can select custom multiplier in SETUP mode 7 (Table 2, Page 10).
Swivelling the speed pot back and forth engages/disengages the CANCEL function when the expression pedal’s
heel is down (4 quick ¼ turns of the Speed knob, left-right swivels). When Cancel function is engaged (by
swivelling speed pot) and active (heel down by default) the system LED will be red. See CANCEL types and options
in SETUP MENU table 2 (Table 2, Page 9).
5.5 PEDAL+ MODE S4
S4 mode is for use with an external footswitch to turn the CANCEL function ON or OFF without tap tempo.
External footswitch turns the CANCEL function ON or OFF. When CANCEL is active the system LED flashes red.
Turning the SPEED pot changes speed of pulsations (full speed range from MIN to MAX, system LED flashes red in
CANCEL mode or green in normal working state).
No tap tempo

5.6 PEDAL+ MODE S5
S5 mode is for use with external footswitch to turn CANCEL function ON/OFF or use tap tempo.
Turning the SPEED pot from MIN to X7 changes speed of pulsations. The whole of X7’s field features the max
speed, meaning you can leave the speed pot’s white tag set anywhere in that field.
If the Speed pot is set anywhere between MIN and X7 the external footswitch turns the CANCEL function ON or
OFF. When CANCEL is active the system LED flashes red, otherwise green.
If the SPEED pot is in T8, T9 or T10 position, tap tempo can be defined with external footswitch
oT8 -> multiplier = x1, system LED flashes red in current tempo
oT9 -> multiplier = x2, system LED flashes green in current tempo
oT10 -> multiplier = CUSTOM (default factory multiplier value = x3), system LED flashes red in current
tempo. You can select custom multiplier in SETUP mode 7 (Table 2, Page 10).
5.7 PEDAL+ MODE S6
S6 mode (FAST/SLOW) is for use with an external footswitch for switching between SPEED 1 and SPEED 2, with or
without Leslie ramp delay. SPEED 1 and SPEED 2 are just labels. In reality it is the user’s choice which of them will be set
slower or faster.
Turning the SPEED pot from MIN to MAX changes SPEED 1's speed.
By pressing the external footswitch, speed changes from SPEED 1 to SPEED 2 or vice versa with programmed
Leslie ramp delay.
In SPEED 1 speed LED is blinking GREEN, and in SPEED 2 speed LED is blinking ORANGE.
If the pedal is in SPEED 2 function and the user moves the speed pot, the pedal automatically switches to SPEED 1
without pressing the external footswitch. A new SPEED 1 can be then set.
By swivelling the speed pot the user enters the procedure for programming SPEED 2 speed and Leslie ramp delay.
5.7.1 FAST SPEED AND LESLIE RAMP DELAY SETUP PROCEDURE
1) Swivel the speed pot to enter the FAST/SLOW programming procedure. Entering that process (after swivelling
the speed pot) is signalled with the LED blinking red and after that the LED will start to blink orange.
2) Turn the speed pot from MIN to MAX to set your desired SPEED 2 value and press the footswitch (or external
footswitch) to save the SPEED 2 value setting. The LED flashes red briefly to indicate that the SPEED 2 value is
being saved, and then goes back to flashing orange.
3) Now turn the speed pot from MIN (0 second) to MAX (10 second) to set desired Leslie ramp delay and press the
footswitch (or external footswitch) to save the Leslie ramp delay setting. The LED flashes red briefly to indicate
that the Leslie ramp delay value is being saved, and then continues to flash green in SPEED 1 mode. The
programming procedure is finished. If the Leslie ramp delay is set to MIN (0 seconds), then PEDAL+ mode S6
works like Two speed mode, without Leslie ramp delay.
Now you can use the external footswitch to switch speed from SPEED 1 to SPEED 2 and vice versa.
5.8 TAP TEMPO VIBE CYCLE SYNCHRONIZATION FEATURE
Many guitarists that use Vibe pedals can sense where the Vibe's modulation/throb starts and ends its cycle.
When you tap a desired tempo, the tap tempo functions will always synchronize the throb pulse to the right phase.
Tapping on an external footswitch (or expression pedal if used) controls the phase of throb pulse.
Tapping just twice is enough to create a tap tempo. Generally, if tapped more, the tap tempo algorithm uses an
average method of the last two tempo periods (last 3 taps). The tap tempo creating algorithm is visually indicated by the
system LED lighting orange. Shortly after the last tap the system LED goes from orange to green or red and indicates that
the tap tempo creating procedure is reset.

6SETUP MODE
SETUP MODE is a system that is used to set and save additional secondary settings embedded in the V-2
hardware/firmware structure (Table 2, Pages 9-11). The average user probably won’t use them, but they are here for all
advanced and curious users and their specific needs.
The basic principle of changing any setting via SETUP MODE is to enter and select the desired SETUP MODE menu,
set the desired parameter or setting, and save it by pressing the footswitch on the pedal.
If for any reason a user wants to quit their current SETUP MODE programming procedure without setting and saving,
the CHORUS/VIBRATO switch should be toggled. The setup procedure will then be cancelled and the V-2 pedal will use its
last saved setting. So, if you are in any setup menu, and toggle the CHORUS/VIBRATO switch, it acts like a general EXIT
command without saving anything.
6.1 HOW TO ENTER SETUP MODE MENU?
The SETUP MODE menu can be entered within 4 seconds after toggling the CHORUS/VIBRATO switch by pressing
the footswitch quickly 4 times. Entering SETUP MODE is visually indicated with LED briefly blinking orange (5x).
The SETUP MODE system has two menus. For MENU 1 the system LED is red, and for MENU 2 the system LED is
green. Each menu has 10 positions for setting different parameter values. Position 10 in MENU 1 is for entering
MENU 2.
After entering the SETUP MENU the user goes through the SETUP MENU positions by rotating speed pot. On odd
positions the system LED is constantly ON, and on even positions the system LED is flashing. After selecting the
desired SETUP MENU position (by rotating the speed pot), that position is selected for editing by pressing the
footswitch. Then the user must use Table 2 below (Page 9) to change the values of their desired settings. After
selecting the desired parameter (by rotating the speed pot again) the user must press the footswitch to save the
new parameter value into the pedal’s memory and then the pedal will continue to work normally.
6.2 EXAMPLE OF CHANGING SETUP PARAMETER
If you don’t have an expression pedal at the moment, but you own a passive volume pedal, and you are curious as
to how the Vibe Machine works with an expression pedal...? Yes! This can be done. With a simple TRS Y cable you can
connect your volume pedal to the Vibe Machine V-2 and use it like an expression pedal. But you must ‘instruct’ the V-2
pedal that you have connected a volume pedal to the PEDAL+ jack instead of a linear passive expression pedal.
The procedure for changing exp. pedal taper types is as follows:
1) Toggle C/V switch and press the footswitch 4 times quickly to enter SETUP MENU 1
2) Rotate the speed pot to position 1 (E1 mark on silkscreen, Table 2)
3) Press the footswitch to enter the expression pedal potentiometer selection menu (E1)
4) Rotate speed pot to position T9 or T10 (volume pedal taper, Table 2)
5) Press the footswitch again to confirm and exit to normal operation
Now you can use your volume pedal as if it were an expression pedal.
6.3 VIBE MACHINE V-2 SETUP MENU OPTIONS TABLE
If the column named “PARAMETER POSITIONS AROUND THE SPEED POT” in Table 2 shows several possible
positions around the speed potentiometer for the same parameter (for example Setup mode 4 (S4): “S6, X7, T8, T9, T10:
MOMENTARY FOOTSWITCH”), that means you can choose any of those positions shown in the table for the same
parameter. So, if you want to set the external footswitch type to momentary type you can rotate and set the speed pot to
any possible position S6, X7, T8, T9 and T10 (and between). After that press the footswitch to save and exit setup
procedure.
On the bottom of the table there are a few Factory modes. Factory modes are used only for adjusting internal
factory parameters, which only we can adjust in production and after production testing processes. They are not important
to the user.

CANCEL DELAY
ADJUSTMENT
(only when
using exp.
pedal)
When an exp. pedal is used to
activate Cancel Mode, this
mode is activated by putting
the exp. pedal in the heel down
position (by default) but it is
not activated momentarily.
Cancel Mode has a slight delay
between putting the pedal in
heel down position and
activating the Cancel Mode. It
is developed this way so the
user can’t accidentally go to
Cancel Mode while using the
expression pedal. When the
exp. pedal goes to heel down
position, the system LED will
first light ORANGE, and after
this brief delay it will go to RED
where the pedal is then in
Cancel Mode.
Rotate the speed pot for
desired delay. At MIN
position Cancel delay is 0,
linear increasing to 1
second at MAX position.

INCANDESCENT
LIGHT BULB
LAMP ON OR
OFF WHEN THE
PEDAL IS IN
BYPASS
Is it possible to turn the
internal photocell’s
incandescent light bulb off
when the pedal is off (in
bypass) in order to prolong the
lamp’s life.
The side effect is that the lamp
needs to reach it’s dynamic
working state, so for a short
while (orange LED lights) after
turning the pedal on the Vibe
Machine will behave as if it is
coming out of Cancel Mode
because the driver, the lamp
and the photocells have to
start working before the proper
vibe effect can occur, Also
check chapter 10.
