From the builder: "My ultra-thin Sydow guitars have solved 2 problems of the trade: Atmospheric conditions of temperature & humidity don't cause these to shift, move, or get out of tune. The ultra thin chamber does not sacrifice sound quality, but rather carbon fiber bracing greatly enhances sound & strength. All Sydow Guitars are ultra thin acoustic-electric with: long lasting frets, dual truss rods, Sperzel thumb-lock tuners keep it in tune, luminous dot inlays on the fretboard’s side, carbon fiber bracing, no heel, custom gig bag. These are extremely easy to travel with, and fit in the overhead bin. The CARBON FIBER guitars: have controls. Most are Black carbon fiber with metallic gold or silver (or other colors) woven in the carbon fiber. I hand lay out the entire body & engineer my Sydow Bridge rise into the soundboards using heat-treated infusion. The carbon fiber guitars can be in a hot trunk or humid conditions without being affected. I hand build these & put many months of extreme attention into each one. I've been a luthier for 40 years, perfecting my art & techniques. These are excellent for stage, concerts, or parlor. Thanks! Trisha & Steve Sydow, Sydow Guitars." Includes original gig bag
