Timeless Instruments is proud to be the first Canadian distributor for Straight Up Strings, made by renowned American author and luthier Roger Siminoff (featured in photo).  We currently stock Straight Up Strings for guitar and mandolin.  Mandola; banjo and resophonic guitar strings can be available upon request. 

Straight Up Strings represents a paradigm shift in musical string technology that focuses on how strings interact with the bridge to drive the soundboard on acoustic string instruments.

Straight Up Strings feature compensated tensions for the fixed bridge on acoustic steel-string guitars, compensated downloads for the movable bridges of banjos and mandolins, and compensated down pressure for the unique supported bridge of the resophonic guitar. String gauges and core/wrap combinations are predicated on where the strings sit on the bridge as well as the tension of neighboring strings.

One of the foremost authorities on musical acoustics and the art of luthierie, holder of eight patents on musical instrument design, Roger has been designing, building, researching, playing, and writing about instruments and their makers for more than 50 years. He has authored eleven books on musical instrument construction and more than 500 articles and columns about artists, instruments, manufacturers, and a wide range of topics on the art of luthierie.
