Martin GPCPA4 in Natural, (Used)

The Martin GPCPA4 is a Grand Performance‑shaped acoustic‑electric guitar built to combine rich acoustic tone with responsive amplified performance. Its solid Sitka spruce top delivers clarity, dynamic range, and punch, while the East Indian rosewood back and sides add warmth and complex overtones, giving the guitar balanced depth across lows, mids, and highs. The natural gloss finish highlights the wood’s character and contributes to a refined visual presence that suits both stage and studio work.

The neck is crafted from select hardwood with a comfortable profile designed for ease of play across diverse techniques, from fingerstyle to full strumming. A modified low‑oval neck shape and an ebony fingerboard with 20 frets and subtle dot markers promote smooth navigation across the fretboard. The Grand Performance body shape, with its slightly larger lower bout and narrower waist, offers excellent projection, a responsive feel, and improved access to higher frets.

For amplified use, the GPCPA4 features Martin’s high‑quality onboard preamp system with a built‑in tuner, making it easy to dial in a natural acoustic voice when plugged in. Controls typically include volume, bass, treble, and phase adjustment, giving players precise control over amplified tone and feedback reduction. Hardware includes sealed tuning machines for stable tuning and an ebony bridge with a compensated saddle for accurate intonation. Together, these features make the Martin GPCPA4 a versatile choice for players seeking robust acoustic tone with dependable performance on stage or in the studio.
