Straight Up Strings is the creative innovation of Roger Siminoff and were developed in 2014, first appearing as Straight Up Strings for mandolin, with banjo and guitar strings following shortly thereafter.
In the late 1970s and into the mid-1980s Roger worked as a consultant to Gibson String Division and Fender/Squires Strings where he designed unique string winding equipment to ensure the wrap wire tension during string winding. Working with the Gibson String Division, Roger created the Gibson "Grabbers" strings, and was influential in the development of the Gibson's "Equa" strings. Roger has also been the man behind the scenes on the development and successful launch of several other private label string brands.
With more than 60 years in luthierie, Roger holds six U.S. Patents on musical instrument designs, has authored eight books on musical acoustics and construction, and has written several hundred articles on luthierie, artists, musical acoustics, finishing, and instrument construction. Roger created Pickin' Magazine in 1973 and then launched FRETS Magazine in 1980.
In 2007, he and his wife, Rosemary, brought on daughter Kali to expand their mandolin and banjo parts business, Siminoff Banjo and Mandolin Parts, and they moved the shop to a larger facility to expand the production space and to realize Roger’s long-time dream to hold Luthierie Camps for budding luthiers. In January 2013, daughters Kali and Amy acquired Siminoff Banjo and Mandolin Parts. With time on his hands, Roger spent a year focusing on the design and development of Straight Up Strings for mandolin which were officially launched in June 2014.
Straight Up Strings are made in the U.S.A. The Company is located in Atascadero - the heart of California's Central Coast area.
Roger Siminoff heads up the design and development of the company's compensated string line.
Rosemary Siminoff oversees the financial, business, inventory and order-processing end of Straight Up Strings.
Kali continued to grow Straight Up Strings to a highly-respected string brand until February 2021 when she decided to pursue other adventures.
