I keep snapping strings at the string locks, what can I do?
The EGS string locks are designed to be elegant and easy to use and, most importantly, to effectively transfer string vibrations to the guitar. The string lock itself is made from aluminium, which is a fairly soft metal, and could be deformed and broken quickly, so all parts that come in contact with the actual string are made from stainless steel.
If your strings break at the string lock, here are some possible reasons and what you can do:
- Using a hex key, it is possible to exert a significant force on the string lock. Only ever tighten the string locks with a conventional "L" shaped key "standing up", ie. use the short end of it to turn it. If you use the long end, it is easy to overtighten the screw and either cut the string, or even damage the wood of the guitar. An approximate torque setting is 1 Nm/0.74Ft-Lb.
- The material in the screw that fastens the string lock to the guitar is hardened steel, and the "star" groove for the screwdriver effectively acts as a knife that can cut your strings. For this reason, our string locks are fitted with a small stainless steel disc that protects this surface. I.e. the string should be pressed between the locking screw and this metal disc. Unscrew the locking screw all the way and ensure that there is a small flat disc at the bottom of the string lock.
- The alloy used in our locking screws is still softer than the material of (most) guitar strings, so it can be deformed and burred over time. Worst case, a burr can become sharp enough that it actually cuts strings during string changes. This kind of damage to the locking screw is easy to polish out with sand paper. Look at the bottom of locking screw and periodically inspect it for damage.
If the disc is missing, or a locking screw is damaged, look inside the other string locks. This problem will only (us knowingly) occur on the high E and possibly B, so you may safely swap screws around or move a metal disc as a short term solution. If you need spares, contact support and ask for replacements.
