Straight Up Strings are designed to compensate for the string loads that impose a torque load on the guitar bridge.
guitar strings drive the soundboard by twisting the bridge.

Straight Up Strings for Guitar

Regular price $ 9.95 $ 0.00

A major paradigm shift in musical string design, Straight Up Strings for guitar is an exciting development that features compensated torque loads to balance the twisting force at the bridge that drives the soundboard. String tensions are compensated for the relative tensions of neighboring strings as well as where the strings sit on the bridge (i.e., inner or outer strings). Manufactured to our demanding specifications and quality control, these unique strings boast a phosphor bronze wrap wire and offer 5 key features:

1) Each string's linear tension is compensated relative to their location on the bridge as well as to the tension of adjacent strings to uniformly control the torque (twisting) action of the bridge that drives the soundboard.

2) Core-to-wrap wire combinations are engineered to improve brightness, sustain, balance, and tone color between the plain B string and the wound G string.

3) Compensated tensions deliver excellent string-to-string balance and improved intonation on all strings.

4) Compensated tensions ensure equal "feel" for picking choking, bending, and fretting.

5) Tensions and torque loads are calculated on a bell-shaped curve to adjust for ISO 226-2003 equal-loudness contours.
