While favored among soloists, gold headjoints are often found in symphonies and ensembles. The timbre of gold is a complex signature that carries in all three registers. It is what acousticians call a "formant" or, in other words, a unique voice, supporting every note. Historically, a gold instrument holds special value. Gold headjoints are available in five styles: Alpha, Arcturus, Bellatrix, Capella and The Platinum Edge.
