impedance stereo audio inputs,

INPUT LEFT

– is

normalled

, i.e. pre-routed →

INPUT RIGHT

when no audio cable is plugged into

IN R jack

. Accept

standard unbalanced TS instrument 1/4″cables, guitar or line levels (up to

12dBV or +/-2V) with soft clipping introduced with higher audio amplitudes.

2. LINE / INSTRUMENT AMPLIFICATION SWITCH:

select

audio input ampliﬁcation: line level (to the left, no ampliﬁcation) or guitar level

(to the right, +11 db or approx. 3.5x gain ampliﬁcation) to have enough guitar

signal.

3. OUT LEFT (MONO)

OUT RIGHT JACKS:

ﬁnal stereo audio

outputs, accept standard unbalanced TS instrument 1/4″ cables.

4. EXPRESSION PEDAL JACK:

assignable expression pedal input.

Accepts standard RTS expression pedal, +5V supplied from the ring.

Expression pedal morphing macro settings are saved for each of the nine

presets separately. For more details on how to assign the expression pedal

jack check

EXPRESSION PEDAL ASSIGNMENT

section below.

5. MIDI IN / MIDI OUT CONNECTORS:

are standard

DIN-5

MIDI

input and output connectors.

MIDI IN

accepts a list of

values (see MIDI

implementation chart at the end of the manual) on the conﬁgured MIDI

channel and MIDI clock.

MIDI OUT

can act as a MIDI THRU or generate

messages and MIDI clock on knob’s movement.

6. DC IN JACK:

2.1mm/5.5mm connector for the power adapter – typical

Boss

® standard, 500mA, +9V, center negative. This jack has internal reverse

protection and voltage rectiﬁcation therefore accepts any DC adapter of 9 to

15 volts of any polarity – center positive or center negative.

7. VOLUME

/CRUSH*

KNOB with LED:

controls the ﬁnal output

volume (this amount is shown with the brightness of the

blue

LED brightness:

fully lit shows 100% volume (by default) and fully oﬀ - silence). Secondary

/CRUSH*

function (pressing or holding

SHIFT

while turning the knob)

enables the

BITCRUSHER

, or in other words: lowers the

SAMPLE RATE

amount out of the

FILTER

chain: full 96 kHz at CCW and crushing to a certain

moment until the audio falls down to noise. The amount of

bitcrushing

shown with the brightness of the

red

LED. When turning this feature, it

radically brings aliasing to the audio signal – use on your own discretion to

creatively add lo-ﬁ ﬂavor. Bitcrusher always stands after the distortion (16)

with cabinet simulator (17*) stages in every routing.

8. DELAY KNOB with LED:

controls the

DRY/WET MIX OF THE

DELAY

eﬀect (that amount is shown with the brightness of the

blue

LED

brightness). Secondary

/TONE*

function (pressing or holding

SHIFT

while

turning the knob) adjusts the tilt EQ after the WET output of the delay chain

Page 6 of 27

(the amount is shown with brightness of the

red

LED), which is useful to

enhance the delays or for dub-delays.

9. TIME/DIV KNOB with LED:

controls the delay time, from short

audio rate repeats CCW and longer taps CW as a primary parameter (the

amount is shown with the brightness of the

blue

LED). Secondary

/MIDI

CLOCK*

function (pressing or holding

SHIFT

while turning the knob from

noon CW) enables the delay to be synchronized to an external MIDI clock

received at the

MIDI IN

connector (5). While the external clock is enabled,

TIME/

DIV

knob acts as a divider / multiplier for the clock with the dividers

written around the knob on the panel and LED ﬂashes

red

according to the

external clock speed.

10. REPEATS

/TAPS*

KNOB with LED:

controls the

REPEATS

FEEDBACK

level of the delay (this amount is shown with the brightness of

the

blue

LED). Turn it fully CW for self-oscillation. Secondary

/TAPS*

function

(pressing or holding

SHIFT

while turning the knob in 3 sectors from CCW to

11 o’clock, 11 to 14 o’clock and 14 to full CW shown with brightness of the

red

LED) changes the stereo behavior of the taps produced by the delay (see

DELAY section below).

11. REVERB KNOB with LED:

controls the

REVERB DRY/WET MIX

level (that amount is shown with the brightness of the

blue

LED). Secondary

/TONE*

function (pressing or holding

SHIFT

while turning that knob) adjusts

the tilt EQ before the reverb tank (the amount is shown with the brightness of

the

red

LED) which is useful to get rid of the boomy low-end

12. DECAY

/PREDELAY*

KNOB with LED:

primary function controls

the decay of the

REVERB’s TAIL

(that amount is shown with the brightness of

the

blue

LED). Secondary function in combination with the

SHIFT

button

controls the

AMOUNT OF PRE-DELAY

- time of the beginning of the ﬁrst

reﬂections of the reverb (the amount is shown with the brightness of the

red

LED). Amount of pre-delay may be perceived as the apparent size of our

‘space’.

13. REVERB TYPE /

/FILTER*

BUTTON:

primary function selects the

reverb algorithm between: hall with shimmer, reverse and spring reverbs.

Secondary function in combination with the

SHIFT

button switches the ﬁlter

algorithms: bipolar SVF LP/HP, BANDPASS or COMB ﬁlter. Selected reverb

and ﬁlter types shown with the columns of LEDs.

14. TAP

/ASSIGN*

FOOTSWITCH with LED:

multi-function foot

switch, can be assigned to various controls via

SHIFT+TAP

combination. By

default assigned to the TAP tempo of the DELAY and

white

TAP LED blinks

according to the delay clock. For more details on modes see the

TAP

FOOTSWITCH ASSIGNMENT

section below.

Page 7 of 27

15. ROUTING BUTTON:

routing chain switching. Each press cycles

through six diﬀerent orders of audio eﬀects (see

DISTORTED REALITY

paragraph below).

16. DISTORTION KNOB with LED:

control over the distortion amount

(shown with the brightness of the

blue

LED). Secondary function in

combination with the

SHIFT

button controls the amount of treble content

after the distortion output. Acts as a 6db/oct

TILT EQ

for low and high

frequencies: clean in the middle (default value), CCW settings being darker

and higher CW settings being brighter (this amount is shown with the

brightness of the

red

LED).

17. MIX

/CABINET*

KNOB:

primary function controls the

GLOBAL

DRY/WET MIX

between the clean input at full CCW and the ﬁnal processed

audio chain output before the

VOLUME KNOB

(7) at full CW (this amount is

shown with the brightness of the

blue

LED). Secondary function in

combination with the

SHIFT

button controls the amount of

SPEAKER

CABINET (or COMBO-) SIMULATOR

applied from clean audio path at CCW

to full at CW (amount is shown with the brightness of the

red

LED). Cabinet

simulator has a set of ﬁlters to quickly sculpt a distorted tone signal from your

guitar without the need for extra amps or pedals. Cabinet simulator always

stands after the distortion stage (16) before the bitcrusher stage (7*) in every

routing.

18. FILTER

/RESONANCE*

KNOB:

primary function controls the

FILTER

CUTOFF FREQUENCY

(the amount is shown with the brightness of the

blue

LED). Secondary function in combination with the

SHIFT

button controls the

RESONANCE

of the ﬁlter (the amount is shown with the brightness of the

red

LED). When the BAND-PASS ﬁlter is selected (13), this knob deﬁnes the

width of the band. In

COMB FILTER

mode the resonance knob is bipolar and

deﬁnes the feedback, adding negative (to CCW) and positive (CW) combs

and at maximum side CW/CCW values enables the resonator.

19. SHIFT /* BUTTON with LED:

adjusts secondary parameters while

held down and when using other controls (shift functions are labeled with

asterisk

/…*

on the panel). When the shift is enabled, its

white

LED is on and

you may see all the LEDs near the knobs switch from blue to red, showing

visually the amount of secondary parameters with their brightness and

allowing you to edit them (or assign modulation as well!).

SHIFT

button has

an additional latched action, so you may press it once to leave enabled and

adjust other parameters while operating with one hand only, however, some

rarely used settings like bypass types or tap assignments require the

SHIFT

button to be held. After you press and hold

SHIFT

, tweak some parameters

and release the button - it turns that button action oﬀ.

20. BYPASS

/PRESET LOAD

FOOTSWITCH:

is essentially a

BYPASS

enable / activate eﬀect / on footswitch. Each consequent press enables and

Page 8 of 27

disables the whole eﬀects chain. When the eﬀects chain is enabled, the

pink

LED

near that footswitch is ON. When the eﬀect chain is bypassed, the LED

is oﬀ and also all the remaining LEDs except the preset selection LEDs are

dimmed. Additionally is used to conﬁrm the load of the newly selected preset

with

PRESET

(24) footswitch.

21. SPEED

/MIDI CLOCK*

KNOB with LED:

controls the frequency

time (speed) of internal

LOW FREQUENCY OSCILLATOR

LFO

from

0.0333

(30 seconds per cycle) at CCW to

15 Hz

(0.0666 seconds per cycle) at CW

as a primary parameter. LED ﬂashes in

red

LED according to internal LFO

clock. Secondary

/MIDI CLOCK*

function (pressing or holding

SHIFT

while

turning this knob from noon CW) enables the LFO SYNCHRONIZATION to an

external MIDI clock received at

MIDI IN

connector (5). In the external clock

mode this knob acts as a divider / multiplier for the clock with the divisors

similar to values around the

TIME/DIV

knob (9) and LED ﬂashes

blue

according to the external MIDI clock speed.

22. LFO SHAPE

/MIDI CHANNEL*

KNOB with LED:

gradually

selects the LFO shape from the list below (the amount shown with the

brightness of the

red

LED). Secondary

/MIDI CH*

function (pressing or

holding

SHIFT

while turning this knob in 16 sectors from CCW to CW)

changes the MIDI channel from 1st to 16th that the pedal accepts and sends

the MIDI data on.

23. MODULATION

/EXPRESSION*

BUTTON with LED:

used to

assign LFO (22) and expression pedal (4). While holding this button (it will

light up) tweak any of the knobs. The amount by which you tweak this knob

from center position to the sides while holding the

MODULATION

button sets

the depth of the selected LFO (22), which will be applied to the assigned

parameter. Secondary combination of

SHIFT

MODULATION

will set the

expression pedal (4) morphing (see 4.

EXPRESSION PEDAL ASSIGNMENT

below for assigning procedure). Same as

SHIFT

(19),

MODULATION

button

has an additional latched action, so you may press it once to leave enabled

and adjust other parameters while operating with one hand only. After you

press and hold

MODULATION

, add some parameters modulations and

release the button - it turns that button action oﬀ.

24. PRESET

/HOLD TO SAVE

FOOTSWITCH:

selects one of 9 presets

(25). Once you select the preset, its LED starts to blink. To load that preset

you have to conﬁrm it with the BYPASS footswitch (20). Loading the presets

will not alter current bypass eﬀect state on or oﬀ.

To save the preset you have to hold the

PRESET

footswitch for longer than 3

seconds. One of the 9 slots will start to blink and you may choose the new

slot to save by pressing the

PRESET

footswitch a few times. To conﬁrm the

preset save in the selected slot press and hold

PRESET

(20) footswitch for

longer than 3 seconds.

Page 9 of 27

🠚 when

SHIFT

button is enabled, pressing the

PRESET

(20) footswitch will

select the presets in the reverse direction.

25. 9 PRESET LEDS:

nine

white

LEDs show the currently selected preset

slot and blink when you select the new one without activating it yet.

VISUALIZING THE REAL TIME VALUES

You may notice each knob has an LED next to it which can become of diﬀerent

brightness of

blue

red

or a mixture of both colors -

fuchsia

When you change the preset or apply modulation you may see those LEDs will

change their brightness or will be

breathing

. Those are real time parameter’s change

visualization while the physical knobs remain motionless.

Since each knob may set various parameters: primary, secondary and modulation

depth, the current physical knob position may not always reﬂect its real parameter

value. That’s where the LEDs come to help.

Primary parameters are written in capitals:

VOLUME, DELAY, TIME, REPEATS,

REVERB, DECAY, FILTER, DISTORTION

and

MIX

are shown with the brightness

of the

blue

LED.

Secondary parameters are labeled with an asterisk

/…*

next to the primary

parameter:

/crush*, /midi clk*, /tone*, /taps*, /predelay*, /reso*, /midi ch*,

/cabinet*

. They and are set in combination with the

SHIFT /*

button and are shown

with the brightness of the

red

LED.

Some parameters have a

bipolar nature

with an important center position:

LP/HP

FILTER

and all

/tone*

controls of the

DELAY

REVERB

and

DISTORTION

pass clear

unaﬀected sound when they are in the center position. The LED becomes

fuchsia

when that certain parameter stands exactly in or crosses the center value.

Also some parameters have

discrete values

: i.e. not a continuous change but a

selection of a few parameters placed around the knob moving range:

/midi clk*,

/taps*, /midi ch*, /midi clk*

. You will see LED shortly blinking

fuchsia

when we

move to the next settings from the list.

DISTORTED REALITY

The power of the

GHOST PEDAL

lies in its stereo complex audio eﬀect chain with

96kHz, 32-bit internal audio processing, consisting of 8x oversampled

distortion

algorithm with

cabinet simulator

and

bitcrusher

, a multimode

filter

delay

reverb

and a modulator -

LFO

. All the knobs positions and settings can be saved and

recalled from 9 presets slots. The order of the three main processing blocks -
