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 two knurled nuts.
Turn the two knurled nuts 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 two knurled nuts clockwise to fix the endpin in this position.
4.2 Mounting the frame bracket
For mounting the frame bracket, gently place the instrument with the fretboard
down on a sufficiently large work surface. Use a soft padding to prevent damages to
the surfaces.
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.
Take the frame bracket from the transport bag of the instrument and insert the
shorter end into this hole provided laterally on the body.
Thread the longer end of the frame bracket simultaneously into the holder provided
on the back of the body. Make sure that the frame bracket sits free of stress on the
body and tighten the holder thumbscrew by turning it clockwise.

4.3 Mounting the bridge
On delivery, the strings of the instrument have minimum string tension between the
machine heads and the tailpiece on the fretboard.
Do not remove the padding under the tailpiece until the bridge is properly mounted
and the strings run correctly in the grooves of the bridge.
Remove the cable tie that secures the strings for transportation.
Remove the two locking wires on the bridge that hold the pads and dampers to the
bridge. Put the bridge into the holder provided on the body top.
NOTICE!
Possible deformation
When pushing up the bridge with the strings having to much tension,
the strings can become overstretched and bridge or body top can be
damaged.
In this case, first reduce the string tension in order to avoid damaging
the strings, the bridge or the body top.
Carefully push the bridge up into a perpendicular position to the body top. Make
sure that all strings run correctly in the grooves of the bridge (the E string has to run
in the biggest groove).
Pre-tighten the strings over the bridge in a way that it is retained in a perpendicular
position.

You can then tune all strings with the machine heads using a tuner device to the cor‐
rect pitch (usually E, A, D and G).

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.
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.
Before connecting the battery, drag out the endpin of the instrument so far that the
battery compartment cover can be opened ( Ä Chapter 4.1 ‘Setting the height’
on page 9).
To open the battery compartment cover, slightly push the locking mechanism
inwards with a finger.
Clamp the power cable with the correct polarity to the battery. Insert the battery into
the battery compartment and close the battery compartment cover. It must audibly
click into position.
Then re-align the endpin to your playing position (
Ä Chapter 4.1 ‘Setting the height’
on page 9).
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
You find the connector for the instrument cable (1/4" jack, mono) at the side of the
instrument body.
Use the switch [ON | OFF] to switch the preamp on or off. The red LED lights up when
the preamp is on.
5.3 Connecting headphones
The connecting socket for the headphones (1/4" jack, stereo) is located above the
battery compartment on the rear side of the instrument.
Use the switch [ON | OFF] to switch the preamp on or off. The red LED lights up when
the preamp is on.
5.4 Adjusting Volume and Tone
The rotary controls to adjust the volume [VOLUME] and the tone [TONE] (treble, bass)
are located at the side of the instrument.

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 3/4 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 A, D and G strings 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.
Before changing the battery, drag out the endpin of the instrument so far that the
battery compartment cover can be opened ( Ä Chapter 4.1 ‘Setting the height’
on page 9).
To open the battery compartment cover, slightly push the locking mechanism
inwards with a finger. 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.
Then re-align the endpin to your playing position (
Ä Chapter 4.1 ‘Setting the height’
on page 9).
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.
