As many of you know, D’Addario has been publishing our string tension data on our packages since 1988. We also published our online String Tension Guide to explain how we achieved those numbers, including proprietary information about the unit weights of our strings. As part of the many initiatives we have been working on this year, and some very exciting ones to which you will soon have access, we reviewed our string calculations to make sure we had the most accurate and precise information available for our users.
Since the original guide was produced to ensure that we would have data available for each string, we began by looking at the many strings we have added to our string lines throughout the years. In doing so, we also made a conscious decision to look into the modeling we used for the original calculations and how we could make them even more precise.
It is also important to note that the tension calculation we provided is only a small part of the much larger calculation that we use to derive our unit weights. We worked hard to ensure that we could get this calculation as close to the actual usage numbers as possible and now believe that we will have the most accurate information that we can possibly provide.
With that being said, the changes in the resulting numbers are derived from two points:
- Tension Calculation and Unit Weight Calculation.
First, we made a change in the Tension calculation by using more decimal precision in our numbers. We eliminated any rounding of decimals that throughout the totality of the calculation could ultimately lead to a greater tension than the actual. Secondly, we remodeled the string Unit Weight calculation itself to allow for a more geometrically accurate number. While some tensions may seem to have changed drastically, (+/- lbs. in some cases) these changes have yielded a much more precise representation of our strings and the tension they yield when tuned to pitch, as well as a much more precise representation than the previous published tensions.
With the recent packaging updates that you may have seen, we have begun to update the tensions published on all of our sets. You will continue to see these changes over the next few months and early into next year. Any new set that has been released this year was released using the updated tension calculations, including the Balanced Tension electric guitar and bass sets.
We feel it is important to note that with all of the work we have put into this project, the numbers that we have published on our sets are still ultimately calculations, and geometric modeling of any physical object is never 100% accurate. We want to ensure everyone that while the calculated tension numbers may have changed, the tensions have not changed due to any modifications or changes to how we manufacture our strings, nor have these calculations caused us to make any changes in our string design or manufacturing processes.
