The JLD/Bridge Doctor system allows new guitar builders to brace the top of the guitar much more lightly than "normal". This makes for a much more lively sounding guitar because the top reacts more quickly and responsively without the restrictive bracing. The JLD system transfers some of the string tension to the tailblock and body of the instrument, so it is not without it's tradeoffs either! Just one luthier's attempt at a new approach.
