Here's a classic-sounding Martin, with built-in electronics for unbelievable plugged-in tone! The "grand performance"-sized Martin Performing Artist GPCPA4R is designed for just who its name says it is... this is the perfect Martin guitar for those of you performing and hitting the stage. Whether you want a fantastic acoustic-electric for your coffee shop shows around tone or you want an arena-worthy acoustic that sounds phenomenal plugged into a massive PA, the Martin Performing Artist GPCPA4 is your pick. This beauty features one of the most popular tonewood combinations: a solid Sitka spruce top and a solid rosewood back and sides. The Sitka gives you the power and strength you want, while the rosewood complements it nicely for a well-balanced sound. Fun fact: this is the kind of guitar that will age incredibly well... Sitka spruce sounds amazing right away, but gets better and better and better and better with time too. It's quite the investment.
