Acoustic blueprinting is a tonal adjustment process that moves beyond
traditional methods, such as moving the sound post on bowed strings,
altering bridges, and checking for proper fit and adhesion.  It isn’t brace
shaving and involves removal of tiny amounts of wood. The physical
approach systematically approaches the overall resonance of the
neck/fingerboard (for violin family), the response of individual pieces of the
body (e.g., ribs, braces, and plates), the bridge (very important), and the
sound hole edges.  The process integrates procedures and techniques
from many workers, some well known, some not so well known.  The
effects include reducing noise, evening up response and balance,
increasing response speed, sweetening tone, and increasing sustain.  
Overall increases in tone quality and carrying power are frequently

The work concentrates on the interior of the instrument and on the bridge
using scrapers and other tools.  The actual amount of wood removed is
usually minor, although some guitars may benefit from more extensive
reworking.  The key is to get all the parts of the instrument working
together, rather than to make the instrument work differently than it already
wants to.  The process takes several iterations.  Turnaround times are
generally less than two weeks.

The name?  We started marketing this process for mandolins, but began
with violins.  Guitars came last.  Ask about other instruments.  We've done
ukuleles, citterns, and a range of other strings.
