How does that help when choosing a guitar? “A lot of sustain will suit a classical guitarist, so that could be from a heavier wood such as rosewood. A flamenco guitar wants all attack, so they are made from nice, light Spanish cedar. “Stiff necks, such as maple, mean more energy goes to the top so there is no effect on tone. Because we’re used to mahogany guitars, it’s an effect in itself.” Jim has made guitars out of ebony, walnut, redwood, olivewood and even Bolivian rosewood. So which is best? “The stiffer the neck, the better I reckon,” says Jim, who jacked in his IT job in London to go to Arizona to pursue his passion and learn his craft.
