Following a precipitous drop in sales between 2008 and 2009, high-end, custom, and boutique acoustic guitars are making an encouraging comeback. Headed into the 2014 NAMM Show, sales of high-end, luthier-crafted and custom acoustic instruments are at a five-year high. Guitar craftsmen and dealers point to a strengthening economy and growing pool of accomplished players for the increase in people searching for (and purchasing) their fretted Holy Grail.
