Straight Up Strings
for Guitar, Banjo & Mandolin

Engineered with compensated torque loads and down pressure for optimum balance.
… every note of every chord

Roger Siminoff’s study of the longitudinal tensions and lateral loads of musical strings has been a special area of interest for more than three decades.

Although the concepts are similar, we distinguish between fixed-bridge instruments (guitar) and moveable-bridge instruments (banjo and mandolin). Our guitar strings are engineered with compensated torque loads (moment of force at the bridge) and our banjo and mandolin strings are a result of measuring and compensating for down pressure of strings at the bridge.

A major breakthrough in string technology, Straight up Strings for Guitar provide excellent string-to-string balance because they are designed to compensate for the force required to move the inner strings of the bridge versus outer strings, as the instrument is played.

Final gauges are the result of determining desired torque load (in inch pounds), and then specifying gauges and core-to-wrap ratios to achieve the proper torque NOT by starting with common gauges and calculating torque. The result is a classic bell curve.

As a final step, we’ve applied ISO: 226-2003 equal-loudness principles to further enhance the perception of an evenly distributed tonal range, as a result of how the human ear and brain perceive sound.

Straight Up Strings for Banjo and Mandolin

Energy Transmission Through Bridges Straight Up Strings by Siminoff

The typical bridge designs on movable bridge instruments such as the banjo and mandolin have design flaws in which some strings sit over feet and have a direct route to the soundboard or head while other strings sit over spaces or arches and have an indirect route.

A major breakthrough in string technology, Straight Up Strings for Banjo and Straight Up Strings for Mandolin provide excellent string-to-string balance because they are designed to compensate for these bridge anomalies.

Engineered to deliver balanced download pressures depending on the strings’ location on the bridge’s saddle.

Final gauges being the result of download measurements, and not the other way around.

As a final touch, we then tempered the gauges by applying ISO 226-2003 equal-loudness principles to further enhance the perception of an evenly distributed tonal range.
