4.1 Setting the height
The endpin to adjust the height of the instrument is fully retracted in delivery condi‐
tion and fixed with the wing nut.
Turn the wing nut counterclockwise to loosen the fixation and the endpin.
Drag out the endpin so far that the instrument can be played at the desired and for
you ergonomically correct and comfortable height.
Then tighten the wing nut clockwise to fix the endpin in this position.
4.1.1 Tuning the strings
Now tune all strings with the machine heads using a tuner device to the correct pitch
(usually C-G-D-A from low to high).

CAUTION!
Possible hearing damage
Making music for a prolonged period and at high volume can cause
hearing damage.
Avoid playing the unit at full volume, especially when using head‐
phones.
NOTICE!
Risk of breakage, possible deformation
When placing the instrument with the fretboard down, there is a risk of
damaging the fingerboard and the tailpiece.
Avoid any compressive load on the rear of the instrument, if it is placed
for the assembly or for service work with the fretboard down on a solid
surface.
Before connecting amplifier or headphones, the rotary control [VOLUME]
must be set to ‘Minimum’ and the preamp switch [ON | OFF] must be set to
‘ON’. This avoids loud crack noises when switching on.

5.1 Connecting and inserting the battery
On delivery of the instrument, a suitable battery is enclosed.
Open the battery compartment cover on the back of the instrument and connect the
lead wire with correct polarity to the battery. Insert the battery into the battery com‐
partment and close the battery compartment cover. It must audibly click into posi‐
tion.
NOTICE!
Possible damage by leaking batteries
Leaking batteries can cause permanent damage to the device.
Take batteries out of the device if it is not going to be used for a longer
period.
5.2 Connecting the instrument cable
The connector for the instrument cable (1/4" jack, mono) is located on the back of
the instrument.
5.3 Connecting headphones
The connector for the headphone (1/4" jack, mono) is located on the back of the
instrument.
Slide the selector switch towards the headphone icon. The switch must be switched
if stereo headphones are plugged in, otherwise the electronic is not activated.
When using a headphone with 3.5 mm jack, you need an appropriate
adapter.
5.4 Connecting audio devices
The connector for audio devices (3.5 mm, mono) is located on the back of the instru‐
ment.

6 Maintenance
6.1 Changing strings
Strings are subject to a natural aging process, which is also affected by the frequency
of use of the instrument. Changing the strings is recommended if the sound quality
of the instrument decreases audibly. Always replace the complete set of strings
(strings of 4/4 length) and always go string by string. In this way you avoid a strong
temporary bending of the neck due to reduced string tension. The bridge also
remains in the correct position and does not have to be readjusted.
1. For example, loosen the run-down E string from the capstan of the machine
head and from the tailpiece.
2. Thread the new E string into the tailpiece, pull it over the bridge into the cap‐
stan bore of the machine head.
3. Hook the string end to the capstan and tighten the string tension slowly. At the
first windings, pay particular attention that the string is taut to the mechanics.
4. Make sure that the string is running correctly through the grooves of bridge
and nut at the upper end of the neck.
5. Slowly increase the string tension until the correct pitch is reached. Use a tuner
or a pitch pipe for reference.
6. Proceed in the same way with the C, G, D and A strings (from low to high) and
then tune all strings again successively to the correct pitch. Note that the string
tension will drop a little and the instrument needs to be retuned several times
until the strings stay in tune.
6.2 Battery change
Replace the inserted battery if necessary (weak output signal) or at regular intervals.
Open the battery compartment cover by sliding in downwards. Remove the battery
and unplug the connection cable from the battery terminals.
Clamp the power cable with the correct polarity to the new battery. Insert the battery
into the battery compartment and close the battery compartment cover. It must
audibly click into position.
Proceed as follows to change the
strings:

8 Plug and connection assignment
This chapter will help you select the right cables and plugs to connect your valuable
equipment in such a way that a perfect sound experience is ensured.
Please note these advices, because especially in ‘Sound & Light’ caution is indicated:
Even if a plug fits into the socket, an incorrect connection may result in a destroyed
power amp, a short circuit or ‘just’ in poor transmission quality!
Unbalanced transmission is mainly used in semi-professional environment and in hifi
use. Instrument cables with two conductors (one core plus shielding) are typical rep‐
resentatives of the unbalanced transmission. One conductor is ground and shielding
while the signal is transmitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference, especially at
low levels, such as microphone signals and when using long cables.
In a professional environment, therefore, the balanced transmission is preferred,
because this enables an undisturbed transmission of signals over long distances. In
addition to the conductors ‘Ground’ and ‘Signal’, in a balanced transmission a second
core is added. This also transfers the signal, but phase-shifted by 180°.
Since the interference affects both cores equally, by subtracting the phase-shifted
signals, the interfering signal is completely neutralized. The result is a pure signal
without any noise interference.
