Straight Up Strings, developed by luthier and acoustician Roger Siminoff, now includes strings for acoustic guitar. Straight Up Strings for Guitar debuted at IBMA’s World of Bluegrass in Raleigh, NC, with demonstrations at the IBMA Business Conference Trade Show, Booth #106, Wednesday, September 30 and Thursday, October 1.

The Straight Up Strings product line, which includes strings for banjos and mandolins, is based on engineered string gauges and core-to-wrap ratios to optimize the relationship between strings and how the strings react to the soundboard. The result is excellent string-to-string balance in tone, sustain, and timbre across different brands and builds of instruments.

In the video above, Roger Siminoff explains how guitar strings work in conjunction with the bridge. On the guitar, the significant force is the torque (twisting) action of the bridge, rocking forward toward the peghead as the strings are played. He explains how he developed Straight Up Strings for Guitar to generate even volume and tone across all strings, bearing in mind that strings toward the center of the guitar require greater torque, and therefore higher tension, compared to those on the outer edges. Siminoff says, “We calculated (guitar string) tensions and torque loads on a bell-shaped curve, which optimizes balance, sustain, and brightness.”

Straight Up Strings will be available September 30 for guitar in light, medium, and heavy gauges. They’re already available for mandolin in medium and heavy gauges and for banjo in light, medium, and heavy gauges. Guitar strings will be available as a single pack ($9.95), 3-pack ($25.35) and 6-pack ($48.35) at and Elderly Instruments (; and in-store at Gruhn Guitars (Nashville) and Sylvan Guitars (Santa Cruz, CA). Shipping October 5. Email amy (at) with questions or feedback.

Roger Siminoff, developer of Straight Up Strings and founder of Pickin’ Magazine and FRETS Magazine, has been focused on strings for nearly 30 years. Kali Nowakowski and Amy Sullivan, Siminoff’s daughters, have owned Siminoff Banjo and Mandolin Parts since 2013 and are responsible for day-to-day operations and bringing Straight Up Strings to market.

A great mandolin duet of Sarah Jarosz’s original tune, recorded live at the Marshall Mandolin Summit.
