The Sound and Feel of Yesteryear

The SonoTone Concert series represents the culmination of over three years of experimentation with various materials and manufacturing techniques by SonoTone founder P.K. Pandey. Having spent more than 25 years on a quest for impeccable tone, both as a studio recording engineer and A/V systems design/build engineer, Pandey’s journey eventually led him to reconsider the fundamental medium and point-of-contact between the player and the guitar, the material source of the instrument’s “voice” —  the guitar strings.

Starting from this fundamental level, Pandey tested different metals, amalgams, and manufacturing processes until he eventually found the hard-won formula, known only to him, which at last recreated the vintage tone and feel of the guitars he remembered playing as a kid.

Unlike many contemporary, machine-made strings produced in bulk quantities outside the U.S. at mass-market, commodity prices, SonoTone Concert strings use highest-quality materials, with additional measures taken throughout the manufacturing process to optimize string behavior, playability, tuning stability and longevity — without using any coatings, so that only the pure elements that make up the string-wire ring out, unencumbered, through the entire body of the guitar.
