Double Bass D Strings

It is unusual for double bass strings to snap. However, if your double bass D string keeps breaking near the machine heads or near the tailpiece, it could mean there is extra friction being applied to the string, causing it to break or snap. We recommend having your double bass examined by a luthier (string instrument repairer) to avoid breakages in the future. When fitting any new strings to your double bass, be sure to slowly tighten the string to avoid breakages.

Using a soft graphite pencil, ‘colour’ in the corresponding groove on the bridge and at the top of the fingerboard (near the pegbox). This will ensure the string slides smoothly through these contact points and does not catch on any part of the instrument. Insert the plain end of the string into the corresponding machine head hole. Tighten the string by winding the peg away from you. Keep the other hand pulling the string away from the machine head to maintain tension on the string. This will keep the string ‘straight’ on the peg. Cross the string over itself once at the start of the tightening process and then wind the remainder of the string towards the machine ‘head’ ensuring that it remains neat on the machine head. You may wish to use a screwdriver with a machine head attachment to speed up this process.

You can refine the tuning with the use of a tuner or tuning fork to help you find the correct pitch. When using the machine heads, turning them clockwise ensures the pitch is raised. If you turn it anti-clockwise, the pitch is lowered. ‘Lefty-Loosey, Righty-Tighty’ is a great rhyme to help you remember.

If your double bass D string sounds "bad", it may mean that you need to use less rosin on your bow, to prevent a raspy tone from occurring, or you may need to upgrade your string. Strings are crafted using precious metals and materials that deteriorate over time. If your double bass D string is over 12-18 months old and sounding bad, chances are it needs to be replaced. We recommend Pirastro Obligato, Thomastik Spirocore or D'Addario Zyex D strings if you're wanting a warm tone. If you're wanting a brighter tone, we recommend Pirastro Evah Pirazzi, D'Addario Prelude or D'Addario Helicore D strings.
