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”).
