stringholder piece on the bridge by
sliding it into the two pin holes.

check that the stringholder sits tightly.
4. Carefully insert the neck into the pocket
on the body.

like shown. With the other hand you
push the neck down firmly until the
Snap System clicks in.

keep slight pressure with your right
hand still on the fretboard to secure the
neck until the strapholder knob is firmly
tightend! (nice and snug)

Assembling
Your guitar is assembled/disassembled under full string tension without detuning the strings first!
It is therefore highly recommended that you assemble/disassemble your guitar just as described below to avoid any
damages! Please read the instructions carefully!
Disassembling and storage in the case
1. Put the guitar on your lap and place
your elbow on the top and press your
right hand on the fretboard like shown.
Then loosen the strapholder knob for
about 5mm.
The neck is still supposed to stay
locked even when the strapholder is
loosened. However, always be ready
for the neck to pop off when you start
operating on the strabholder knob!
2. To release the neck connection push on
the strapholder knob. The neck then will
spring up immediately! Hold the neck
down firmly with your right hand while
pushing on the knob in order to let it
come up slowly and securely.
3. Totally release the string tension now
by lifting the neck up and out of the
pocket on the body.
4. Keep the neck end away from the body
to avoid damage while you carefully
pull the string holder off the bridge. Pull
nicely parallel to the bridge like shown.
5. The neck fits into the bottom of the
backpack below the protection layer.
It‘s supposed to go in up side down
with the string looped around like
shown.
6. The neck is then covered with the
protection layer and the body goes on
top with the front side up.
The lit of the backpack is also a neck rest
to lay the guitar on the floor when it is
assembled.
The shoulder straps can be pulled tight
when not in use.
The B-C Backpack has three different
outside compartments for accessories.
1. Loosen the string until there is a good
slack.
Changing strings on the Gotoh self locking tuners
All B-Compact are equipped with special Gotoh self locking tuners to keep the strings from coming off
the tuner posts when the neck is removed and to keep the strings better in their original tune.
2. Take a coin or screw driver and turn the
tuner post a 1/4 turn against the string
tension just to loosen its pressure on
the string.
It‘s the oposite way on right and left
side!
3. Keep turning the tuner knob as you
would loosen the string. This will bring
up the tuner post and you can pull out
the string easily.
4. Pull the new string through the hole on
the bridge and the hole at the nut of the
guitar neck.
5. Loosen the tuner post until you can
easily see through the hole. Then pull
the string through the hole and keep
some tension on the string while you
start turning the tuner knob as you
would tune up the string.
After a few turns the string will
automatically lock itself and you can
bring it up to its tune.
6. Lastly just clip off the string... done!
Retightening of the tuner post with a
coin is not necessary, this rather
causes the string to break easily if it
gets pinched too much.
Tunings and string gauges
For all full scale models:
All full scale guitars are built for standard E tuning and come with a light set of 012-053 strings. If you use havier strings please be
aware that you may have to adjust the trussrod of the neck and maybe lower the saddle on the bridge a little bit.
(as described on next page).
For the small body short scale models:
The small body short scale models are delivered tuned to standard E, but the string tension is rather on the loose side. They also come
with a light set of 012-053 strings, but you can also use a medium set of 013-056 to compensate for the looser tension.
However, the short scale models bring out their full potential when tuned a bit higher (max. to G), but in this case we highly recommend
using light 012-053 strings only! You also may have to adjust the trussrod of the neck in this case to keep the action low.
(as described on next page).
Adjusting the „action“
All B-Compact guitars leave our shop with the action set up with a distance between the 12th fret and high E string of 1,8mm and
2,2mm on the low E string. Should the action have changed due to humidity changes or because the guitar has been asssebled for a
longer period of time, all B-Compact guitars are equipped with a 2-way adjustable trussrod to correct the neck bow. To check the neck
bow you can push down a string on 1st and the 14th fret using the string as a „straight edge“. There should be a gap between the string
and the 5th fret of max. the thickness of a credit card (0,5mm). Is the gap too big, you need to straighten neck by tighten the trussrod
with a 4mm Alen key clockwise. If you get too much buzzing while playing, the neck might be too straight und you need to turn counter
clockwise.
The trussrod is reached though the hole on the neck end, therefor the neck needs to be taking off to do the adjustment. To check the
change of the neck bow put the neck back on and push down the same string again to inspect the distance by the 5th fret.
Is the action still too high you can lower the bridge saddle by sanding it down on the bottom side with a hard sanding block, nicely
square and parallel. Basically you need to take down the double hight of the amount you want the strings be lower at the 12th fret.
Please only do this if you know what you‘re doing, otherwise contact us first or go see your next guitar repair shop.
Storage
Try to keep your guitar in a humidity range between 40-60% (normal) and avoid extremes. To be out of this range is not a problem if it is
not for weeks at a time.
We recommend keeping the B-Compact disassembled and stored in the case if it won't be played for a few weeks. In the case, the
guitar is better protected from temperature and humidity changes. It is also better for the top and neck not to be under constant tension
as it might change the “action” (distance between fretboard and strings) after some time.
However, you can also keep your guitar assembled at home over longer periods of time, but you may have to adjust the trussrod in the
neck and maybe lower the bridge saddle after a while to keep the action low. (Read the next topic “Adjusting the action”).
