In the A3R acoustic-electric guitar, Yamaha offers a vintage look with enhanced volume in the low-mid ranges, due to new scalloped bracing for the top and shorter bracing on the dreadnought's back. With a solid Sitka spruce top and solid rosewood back and sides, the guitar sounds fantastic. The A3R takes full advantage of Yamaha's acclaimed SRT2 pickup system for recording and stage performance. You get volume, treble, and bass controls (with auto feedback reduction), and blend control allows you to balance between the piezo and SRT2 preamp signals for your own distinctive tone.
