![]() Finally, tune to pitch and apply string tension evenly. Last, install and tighten the 1st and 6th strings. Then add and tighten the 2nd and 5th strings. When restringing its best to tighten the middle strings first so pressure is applied to the saddle center. If a piezo is offset strings are not making contact with the individual sensors in the piezo pickup. If uneveness is present then sound will be unbalanced and requires that the slot be leveled with a leveling tool.Ī piezo must be correctly aligned with the guitar strings. Finally, the saddle bottom should be squared.Ī saddle slot (bridge slot) must also be flat. ![]() Also, the saddle ends should be rounded smooth as opposed to square. ![]() If one cannot gently lift a saddle from the slot then the saddle is binding.Ī string saddle should be clean of debris and able to be re-inserted in the slot without binding or being forced in the slot. A jammed or overtight saddle in the slot will impair the piezo sound or cause a hum. Moreover, the saddle must be flat, square and true in the saddle slot. There must be even pressure from each string to the piezo element/pickup. The most important of these elements is the saddle. If any one of these elements are out of balance it throws off the balance thus poor or faded string sound(s). Proper balance of a piezo requires a precise fit of the string saddle, the saddle slot, the piezo, and the strings. ![]() Piezo pickups are placed under the string saddle to convert string and top movement into an electrical signal that can be amplified. Piezo ceramics, or crystals, are materials that generate an electrical charge when subjected to stress. Below is good information to understanding a piezo system. Recently, we had discussion with the head luthier/technician at the Taylor Guitar Factory about uneven or unbalanced sound happening on acoustic guitars with a piezo system. The stringing of an acoustic electric guitar with an undersaddle piezo pickup suggests a different technique other then following the procedure from the former article: Stringing an Acoustic Guitar. ![]()
