  • Page 5: Care

    CARE The Berlin family has a very light construction, with very thin plates that can be easily damaged. This is not a conventional archtop with plates that triple the thickness, virtually indestructible. In fact, you could open a hole ⚠ ⚠...
  • Page 6 Try to clean the strings after use with a dry clean cloth.  Avoid the contact with alcoholic beverages. If it happens sometime,  absorb them with a dry cloth without rubbing. Connect your instrument only to reliable equipment that have a ...
  • Page 7: Maintenance

    MAINTENANCE Changing Strings You should do this… Whenever the strings don’t sound bright, are worn or dirty or have tuning problems in certain areas of the fretboard. Necessary tools and materials: Pliers and strings. Method: Loosen one string. To untie it from the machines and the tailpiece, ...
  • Page 8: Adjusting The Bridge Height

    Adjusting the Bridge Height You should do this… Whenever there are buzzes in wide areas of the fretboard. The height may be lowered if the action is too high and there are no buzzes. Necessary tools: Small Hex (Allen) key, supplied with the guitar. Method: Depending on the problem affecting more the bass strings than the treble...
  • Page 9: Adjusting The Compensation

    Adjusting the Compensation This procedure must be performed so that all the notes and their octaves sound reasonably in unison, independent from their position on the fretboard. A guitar that is not well compensated can be especially unpleasant when playing chords that mix notes fingered in high frets with open strings.
  • Page 10 bridge will have to be moved closer to the tailpiece. Otherwise, move it further away from the tailpiece (see drawing). Check the same for the fifth string, but  this time try to move only the bass side of the bridge, as you should not modify its position for the string that you adjusted first.
  • Page 11: Adjusting The Truss Rod Tension

    Adjusting the Truss Rod Tension You should do this… When there are buzzes but the action is high. This has three main probable causes: - Change of the tension exerted on the neck, usually following the change of the string gauge or alternate tunings. - Wood adaptation to the strings/truss rod tension and compression forces.
  • Page 12 If the gauge doesn’t fit, turn the adjustment nut with the large  Allen key, counter-clockwise as seen from the peghead end, an eighth of a turn or less (see drawing). Wait until the following day, then adjust  the height of the bridge (Page 6) and repeat the process.
  • Page 13: Adjusting The Pickup-String Clearance

    Adjusting the Pickup-String Clearance You should do this… When you notice that the amplified sound of a string or group of strings is louder or weaker than the others, or when the output of the pickup is too high or too low. This adjustment is only for the magnetic pickup. Necessary tools: You will need a Phillips screwdriver for the mounting screws (A and B in the drawing) and a Hex (Allen)
  • Page 14: Replacing The Battery

    Bronze wound strings have a fantastic acoustic tone, but their volume is quite low when used with magnetic pickups. The plain strings in the set (usually the first and second) will have a much higher volume, resulting in a very strong imbalance. The logical way to correct this problem is to raise the polepieces of the wound strings and lower the polepieces of the plain strings, trying to equalize their output.

    Electric Controls There are controls both at the pickguard and at the tailpiece: Magnetic Pickup Tone Pot Master Volume Pot Magnetic Pickup Volume Pot Piezo Pickup Volume Pot...
  • Page 16: Deciding On The Amplifier

    The independent volume controls for the two pickups, magnetic and piezo, are located at the tailpiece. The master volume, which allows you to set the volume of both pickups at the same time, is located below the pickguard, just as the tone control for the magnetic pickup. These two mimic somehow the ones that you find in many single-pickup archtops, with some subtleties: The output of the guitar, controlled by the master volume, will have a...
  • Page 17: Connecting Your Guitar

    Connecting your Guitar The Berlin V has two jacks at its side, shown here: #1 is a Mono jack and #2 is a Stereo jack, both for 1/4”plugs. We’ll explain a few things about plugs now. There are many different types, but conventional electric guitars use 1/4”...
  • Page 18 If there is another 1/4” TRS plug, this is usually known as Stereo  Cable. It carries two signals from the guitar to some other equipment that will take care of both. If there are two plugs, no matter their type, this is usually called ...
  • Page 19 This has the advantage that you don’t need the battery to make it work. It won’t use it either, so you may leave the cable connected permanently. Guitar Cable in #1, Guitar Cable in You can route the signals to two separate amps/amp channels, for your piezo and magnetic pickups: #1 is the magnetic, #2 is the piezo.
  • Page 20 can use even if the amps are separated by meters. If you forgot to bring it to the gig, then use two cables, as in (b). You must remove the cable when you are done playing; otherwise the battery will deplete. There is a fourth possibility that is not exactly useful, but it is good to mention it in order to highlight a small detail in the operation of this guitar: Guitar Cable in #1, Insert Cable in #2...
  • Page 21: Anti-Feedback Plug

    Anti-Feedback Plug All Berlin guitars have a very responsive soundbox, prone to feedback easily in high volume situations. The anti-feedback plug is a device, included with all Berlin guitars since 01/2022, that can be pressed gently into the soundhole, closing the soundbox and raising the feedback threshold.
  • Page 23: Specifications

    Specifications Variable Materials: Wood: Usually maple and spruce for the soundbox and maple for the  neck. The fretboard, peghead face, bridge and tailpiece are usually made of ebony. The pickguard/pickup ring skin is made of ebony most times (its core is always fiberglass), and the pickup is usually made of ziricote or ebony.
