Independent shopping perspective
The 1778TX-5-G is a right-handed acoustic-electric with a solid A-grade Sitka spruce top, scalloped X-bracing, and a bass-side multi-soundhole design. Its mid-depth Lyrachord GS body keeps the build focused around Ovation’s composite-body format. For amplified work, the OCP-1K pickup feeds an OP-Pro preamp with tuner, EQ, phase switch, feedback rejection, and notch filter. A flat maple neck, pau ferro fingerboard, and 1.69-inch nut width define the playing layout.
