COSTALAB LABYRINTH
Labyrinth pedalboard is designed to switch pedal effects in true-bypass.
You can activate/deactivate up to 10 pedals (or pedal sequences) individually (SB Mode - Stompbox
Mode) or in programmed mode (MEM)
With LABYRINTH you can:
- Maintain the signal quality along the effect path.
- Easily change complex sounds without having to switch on and off individual pedals
- Switch amp channels
- Manage an external multieffect processor or pedals via MIDI
FEATURES
- 10 true bypass loops (send/return) for “front amp” effects or: 7 true bypass loops (send/return) for
“front amp” effects and 3 “stereo” true bypass loops for amp send/return effects.
- 3 control switches and analog TAP TEMPO out.
- Programmable Amp A/B output.
- 10 “stomp box” buttons with status LED. These buttons directly activate effect loops. (Stomp Box
Mode)
OR
- 10 preset buttons (1-10) to recall the effects combination and switch settings. MIDI (MEM Mode).
- UP/DOWN buttons for MIDI bank change (1-5, 6-10, 11-15, 16-20, 21-25, etc.). Also used for MIDI
channel change and switch function selection.

OPERATING MODES
Labyrinth could be used in two different modes:
“SB” (Stomp Box) Mode
In this mode, the 10 dedicated buttons include or exclude the relative pedals in the signal path.
When “SB” mode is selected, “SB” is displayed on the screen and the leds above the stomp buttons
indicates which effects are in the signal path.
“MEM” (Preset) Mode
MEM Mode (Memory Preset) allows you to recall any effect combination previously saved. You can
store up to 520 presets. Every preset can be modied in real time by switching in SB Mode and
using the loop buttons.
In “MEM” mode the display shows the current preset with a letter “A-Z” (Bank) and a number from
1 to 10 (Preset).
Using 1 to 10 buttons you can recall the relative preset of the current Bank. By pressing the “UP” or
“DOWN” buttons you can select the bank from Ato Z(1-260) or from A to Z (261-520).
N.B. When choosing a new bank, the current preset is not changed until you select a preset of the
new bank.
Switching between “SB” e “MEM” mode is done by briey pressing the “Menu/Enter/SB.MEM”
button.
If the “MEM” Mode is active, the green indicator “SB-MEM” under the “Menu/Enter/SB.MEM”
button is lit.

STORING A PRESET
1) Enter “SB” Mode by holding “Menu/
Enter/SB-MEM”
2) Press the buttons corresponding to the
pedals you want to insert in the signal
path. Led indicators will light up.
3) Press and hold the “Menu/Enter/SB-
MEM” button until main menu is displayed.
4) Again, press and hold the “Menu/Enter/
SB-MEM” button until “Write to” appears
on the display.
This sequence represents an “on the y” storing process, to save the patch that is selected in that
moment.
5) Use UP and DOWN buttons to select the bank where to save the new patch. Use 1 to 10 button to
choose in which memory location store your preset.
Simply press “ENTER” button to conrm. “COMPLETE” will appear on the display to conrm the
saving of the preset in the pedalboard memory.

MENU
In SB Mode, hold the MEM button until led SB/MEM
blinks. Edit Menu has many conguration options. The
display always shows the last option selected. Select
which parameter to modify using the UP/DOWN buttons,
press ENTER, then use UP/DOWN buttons to set the
value and eventually press ENTER again to conrm.
A description of editable parameters is provided below.
Effect On/Off
Allows effect loops (from 1 to 10) to be included in the
signal path.
Press again the ENTER button, the screen shows “edit”
indicating that you are in the effect choose mode.
Pressing number switches 1-10 turns each effect loop
on/off.
Corresponding LEDs indicate the loops included in the
signal path.
Buffer 2
Buffer located after loop 7. It can be activated/
deactivated.
If activated allows to control the signal level of the effect
chain usually connected to the Send/Return of an amp
via an expression pedal connected to EXP2 jack.
The pedal value controls the amount of signal owing
into the effect chain connected to the amp Send/Return
maintaining reverb and delay tails.
Pedal position is stored in the patch. Therefore it is
possible to set a patch main volume for each individual
patch.
Switch 3
Analog switch on SW3-TAP jack. activable only in MEM
Mode.
When this parameter is ON the analog switch is activated
and allows to switch amplier channels.
When a patch is recalled and the parameter is ON, the
switch is closed.

MENU
Switch Mode
Set the working mode of the 3 analog switches:
Options are: Latch, Timer 250ms, 500ms and 1000ms.
In Latch mode the switch is closed and held closed until
another patch is selected.
In the other modes, the switch is closed and held closed
for the amount of time selected.
These modes are useful for devices that use “Unlatched”
pedals.
Amp Select
Labyrint features two separate outputs for two amps or
as stereo outputs of stereo effects connected to loops 8,
9 or 10.
This parameter selects the active output: A, B, or A+B..
To use Labyrint in stereo select the A+B mode.
EXP PEDALS
Pedal 1/2 On/Off
Activates the EXP1 pedal on the IN-B input buffer or
EXP2 pedal on buffer 2.
Once the pedal is active, the signal is fully analogic
controlled using the expression pedal connected to the
relative jack.
Pedal position is stored into the patch and recalled when
the patch is selected.
Using EXP1 Pedal
This funcion is used to have different sounds depending
on the pedal position.
For example let’s store a patch with the loop 2 ON
containing an Overdrive with a high gain.
Set ON the EXP1 pedal and move the pedal position
at 1/4. The resulting sound will be a light crunch as we
lowered the guitar volume knob. Then store a patch with
these settings. Now move the pedal position at 3/4 so
the resulting sound will be a higher gain one. Store this
sound as a new patch.
Set now the pedal at maximum, the sound will be a lead
sound corresponding to the Overdrive setting. Let’s
store this third patch.
Select these 3 different patches to recall a Lite Crunch,
Crunch and Lead sound without even touch the pedal
knobs.
Input Volume
Pedal 1/4 lite crunch
Pedal 1/2 crunch

OTHER FUNCTIONS
Factory Restore
In order to perform a factory reset, power on the
pedalboard while holding switches 1 and 6. The device
will now reset, indicated by the “Init Memory” prompt in
the LCD display. Wait for the factory restore procedure
to nish (“Complete”).
N.B. Please note that the factory restore will delete all
user presets and data. It is strongly suggested to perform
a backup with the Labyrinth Editor software before
proceed to the factory restore.
Update Firmware
With “Boot Loader” software downloadable from
the Costalab website is possible to update Labyrinth
rmware to the latest version.
Connect Labyrinth to a PC using the Roland UM1 MK2
MIDI-USB interface via MIDI jacks.
To enter boot-loader mode, power the pedalboard
while holding switches 6 and 7.
When the display shows “Bootloader”, you can proceed
with the update.
Firmware Version
Start the pedalboard while holding switch 2 to verify the
rmware version installed.
Expression Pedal calibration
Pedals connected to jack EXP-1 e EXP-2 can be calibrated
by powering on the pedalboard while holding switch
4. Follow the indications on the screen to perform a
complete calibration.
