The Natural Concerto Signature

15” Acoustic Archtop



This Custom Ordered wide nut Natural Hand Carved Concerto Acoustic Archtop was ordered by a player to fit his needs. the chosen nut width of 1-7/8” was to give more room and string spacing for complex chords and the large hands of the player itself.

We went for an all natural finish, on a very wonderful choice of tonewoods that makes for a really expressive and responsive, versatile instrument that shines in many styles of music and guitar playing. A side soundport was added for a more intimate relation between the player and his instrument. It is, like it’s base model the Modern Signature, completely assembled like a String Quartet Instrument.

The braces are Rancourt Guitars own original design, hand carved in the top to enhance the harmonic response & complexity, it’s power,  to reduce loosing vibration through glued straight joints and to give a more balance natural  tone and resonance to a wider frequency range throughout the top.

The result is a highly responsive instrument with a very large dynamic range and a beautiful articulate voice
