XT-1: One Pedal, Infinite Guitars!
Thank you for buying the new XT-1 by SIM1. This is the first guitar
profiling system that makes it possible to play your electric guitar with
the sound of any other existing guitar in the world.
This is made possible by our proprietary technology “Smart Tone
Shaping” (protected by patent) and what we call “Learning
procedure”. This procedure allows the SIM1’s XT-1 to shape the sound
of the guitar of your dreams around your own guitar sound. The XT-1
does this by matching the tone of your guitar/s (hereafter Source
Guitar) and the tone of the guitar you would like to emulate (hereafter
Target Guitar).
The Learning Procedure is achieved by recording inside the pedal an
ascending chromatic scale starting from the E (6 open string), making
a progression of 6 notes per string in 80 seconds (36 notes in total).
Read carefully the related chapter at pages 11-17 of this manual for
detailed instructions for this procedure.
Since most of guitars in the market have 2/3 pickups, the procedure
allows you to choose whether to record 1 or 3 pickups (neck, mid or
mid position, bridge). We recommend using a perfect matching
among the pickup of your source guitar and that one of the target
guitar. In this way the tone emulation will be 100% accurate!
There's nothing in the market with such a reproduced authentic
sound, which is the result of years of research. XT1 is the only pedal
able to grant to musicians an infinite variety of guitar sounds, without
any latency in terms of signal response, and without the need of any
invasive item to be placed on your guitar body.

Use
Learning Procedure N.1: “Shop Mode” – Record the sound of a Source Guitar
& Reset the target sounds to those of Factory Default Settings
The “Learning Procedure” must be used for the XT-1 to recognize the sound of
your guitar (Source Guitar) and to make it possible for the emulation of all
target guitars included in the device. The “Shop Mode” allows you to record 1
or 3 pickup positions of the Source Guitar, and automatically assigns this Guitar
to all pre-sets of XT-1. At the same time all pre-sets sounds will be restored into
those ones of Factory Default.
1. Connect the Source Guitar to the Input Jack (7) of XT-1 and the Output Jack
(8/9) to the amplifier/Mixer as described in the “Connections Section”;
2. Switch the pedal On (10), and wait until the system finishes to load and the
name of the guitar placed in the first channel, it will appear in the display (1);
3. Make sure your Source Guitar is in tune;
4. Move the Pickup selector to the Neck position;
5. Hold simultaneously the three Switches of the pedal (3,4,5) for 5 seconds.
The system will ask you the number of pickups you would like to record (1 or
3).
6. Press the “Down Switch” (4) to record only 1 pickup or “Up Switch” (5) to
record 3 pickups. Then a countdown will start on the display (5 seconds to start
Learning PU Neck);
7. When the countdown is finished the device will start recording (Display:
Learning 1/80...2/80...3/80 - Hold Up To Abort). Play an ascending chromatic
scale starting from the E (6 open string), making a progression of 6 notes per
string (80 seconds to make 36 notes in total, 2 seconds per note is
recommended) –see the tab below.

11
First option: Source Guitar with 1 pickup sound:
8. In case your Source Guitar has 1 pickup only, play the chromatic scale as
described in point 7 (fig. 1).
9. After 80 seconds of recording the system will make a “quality check”, based
on the good execution of the chromatic scale (the system controls if each of
the requested notes have been played for their adequate duration). Then you
will be asked to save, or not, the recording.
10. If you are not satisfied with the quality rating, then press the “Down switch”
(4) and repeat the chromatic scale (point 7).
11. If you are satisfied with the quality rating, then press the “Up switch” (5).
The system will make a computing process of the sounds loaded in the XT-1
(Display: Computing Progress 00%...100%).
12. At the end of the Computing Process, press the “Up switch” (5) again to
definitely end the Learning procedure.
13. At this point the Target Guitar profiles included in XT-1 will be associated
to the pickup you decided to record and will be modelled around the sound of
it. Scroll up and down the Switch selectors (4,5) to test the variety of sounds.
14. For any reason, during individual Pickup recording, it is possible to stop the
Learning Procedure, just holding for 2 seconds the Down Switch (4).

12
Second option: Source Guitar with more than 1 pickup sound
15. In case your guitar has more than one pickup, move the selector to the Neck
Pickup position;
Then make the chromatic scale as described at point 7 (fig. 1).
16. After 80 seconds of recording the system will make a “quality check”, based
on the good execution of the chromatic scale (the system controls if each of
the requested notes have been played and their adequate duration). Then you
will be asked to save, or not, the recording
17. If you are not satisfied with the quality rating, then press the “Down switch”
(4)nand repeat the chromatic scale (point 7).
18. Repeat the procedure described at point 7 for the recording of the Mid
Pickup position (Display: 5 seconds to start Learning PU Mid –then: Recording
1/80...2/80...3/80 - Hold DOWN To Abort);
19. Repeat the procedure described at point 7 for the Bridge Pickup recording
as well. (Display: 5 seconds to start Learning PU Bridge –then: Recording
1/80...2/80...3/80 - Hold DOWN To Abort);
20. When the recording procedure of the three Pickup positions is finished, the
system will analyse the Source Guitar sounds (Display: Computing Progress
00%...100%)
21. At the end of the Computing Process, press the “Up switch” (5) again to
definitely end the Learning procedure.
22. At this point the Guitar tones included in XT-1 will be automatically
associated to the corresponding pickup of your guitar and will be modelled
around the sound of it. Scroll up and down the Switch selectors (4,5) to test the
variety of sounds.
23. For any reason, during each Pickup recording, it is possible to stop the
procedure, just by holding for 2 seconds the Down Switch (4).
With the Shop Mode XT-1 creates 3 Source Guitars (Guit1, Guit2 Guit3), each of
them corresponding to a different Pickup. The system will automatically assign:
- the Source Guit1 (Neck Pickup) to all the Target Guitars with the emulation of
a Neck/Piezo Pickup sound or Mic recorded sound;

13
- the Source Guit2 (Mid Pickup) to all the Target Guitars with the emulation of
a Mid or Mid Position Pick Up sound;
- the Source Guit3 (Bridge Pickup) to all the Target Guitars with the emulation
of a Bridge Pickup sound;
For each Target Guitar Profile, while performing, is recommended to switch the
Pickup position of the Source Guitar to that one suggested on the display. This
allows to reach a sound as much close as possible to that one of the original
Target Guitar.
Kindly note that with this procedure all the other source guitars previously
stored in the pedal will be automatically cancelled.
Learning Procedure N.2 “Learn&Play Mode” - Record the sound of a Source
Guitar
The “Learn&Play Mode” allows to record 1 or 3 pickup positions of the Source
Guitar, and automatically assigns this Guitar to all pre-sets of XT-1. In this case
the pre-sets sounds won’t be changed into those ones of Factory Default.
1. Connect the Source Guitar to the Input Jack (7) of XT-1 and the Output Jack
(8/9) to the amplifier/Mixer as described in the “Connections Section”;
2. Switch the pedal on (10), and wait until the system will finish to load and the
name of the guitar placed in the first channel will appear in the display (1);
3. Make sure your Source Guitar is in tune;
4. Switch the pickup of your Source Guitar to the –Neck Pick Up;
5. Hold simultaneously the “bypass” and “down” switches of the pedal (3,4) for
5 seconds. The system will ask you the number of pickups you would like to
record (1-2 or 3).
6. Press the “Down Switch” to record only 1 pickup or “Up Switch” to record 3
pickups. Then a countdown will start on the display (5 seconds to start learning
PU Neck);
7. Repeat the procedure from point 8. to point 14. (Source Guitar with 1
pickup), or from point 15. to point 23., of the “Shop mode”, to complete the
learning procedure;

14
8. Now the source guitars in use created will be named with a progressive
number (i.e. Guit4, Guit5, Guit6). The previous source guitars are still stored
into the device and they can be recalled through the Configuration Software or
through the App for IOS or Android.
Learning Procedure N.3 “Add-Source Mode” - Record and Store one pick-up
at a time as Source Guitar
The “Learn&Play Mode” allows to record 1 pickup positions of the Source
Guitar and store it to XT-1. In this case the target sounds on the pedal won’t be
automatically assigned to this Source Guitar. You should do it manually using
the “Configurator Software” or the App for IOS and Android.
1. Connect the Source Guitar to the Input Jack (7) of XT-1 and the Output Jack
(8/9) to the amplifier/Mixer as described in the “Connections Section”;
2. Switch the pedal on (10), and wait until the system will finish to load and the
name of the guitar placed in the first channel will appear in the display (1);
3. Make sure your Source Guitar is in tune;
4. Switch the pickup of your Source Guitar to that one you would like to store
in XT-1;
5. Hold simultaneously the “up” and “down” switches of the pedal (4,5) for 5
seconds.
6. A countdown will start on the display (2 seconds to start Learning);
7. Repeat the procedure of point 7. of the “Shop Mode” to complete the
learning procedure;
8. Now the new created Source Guitar will be named with a progressive
number, depending on the amount of Source Guitars present in the device (i.e.
Guit4, in case Guit1, Guit2, Guit3 were already stored).

15
True Bypass
When the True bypass mode is activated the check indicator (2) will light in red
colour and the writing “True Bypass” will appear on the Display. Now the signal
is not processed in any way, and the sound will be the original one of the Source
Guitar. The second line of the display shows the guitar/pick up you are
supposed to play on the Source Guitar.
Pressing again the Bypass switch, the red light of the check indicator will turn
off and the sound will shift to that one of the target guitar in use.
USB Port
XT-1 is equipped with an USB Port 2.0, which must be used with the USB stick
to transfer the sounds (both source guitars and target guitars) from XT-1 to the
Configurator Software, make your own set up, and return them back to XT-1 to
make the upgrade of the device.
Back Up procedure
Insert the USB key (13) in the USB port (11), then hold for 5 seconds the Downs
Switch (4). At this point on the display will appear “Back Up in progress”. Leave
the USB Key inserted into unit until all the data will be loaded to the stick, and
“Done!” will appear on the display.
Now it’s possible to extract the stick and to insert it to the PC/MAC to import
the Back Up of your XT-1 on the Configurator Software.
Upgrade procedure
Once all data have been saved from the Configurator Software to the USB stick,
insert the key (13) in the USB port (11), then hold for 5 seconds the Up Switch
(5). At this point on the display will appear “Upgrade in progress”. Leave the
USB Key inserted into the unit until all the data is forwarded to XT-1, and
“Done!” will appear on the display. Now it’s possible to extract the stick.

16
Reset Procedure
To reset the device to the factory default settings you must hold
simultaneously the Bypass and Up Switches (3-4) for 5 seconds. You will be
asked to confirm this procedure: press Up Switch (5) to definitively reset, Down
Switch (4) if you don’t want to reset. After the reset procedure all the Source
and Target Guitars inside XT-1 will be restored to those of factory default
setting. It’s strongly suggested to make a backup before making this procedure,
in order not to definitively lose Guitars (Source or Target).
Serial Number Code
To see the Serial Number Code, a special code different for all devices, hold for
5 seconds the Bypass Switch (3), and it will appear on the display. This code is
useful to register your device in the SIM1 Web-Store or App. This procedure
will allow you to use in your XT.1 pedal the new sounds you will buy, or you will
download for free from the community. Please note that if you do not input in
a correct way the Serial Number Code on the Web/App, the downloaded
sounds will not be correctly installed in your XT-1 device and they will not work
properly.
