Gretsch G9200 Boxcar Round-Neck Resonator GuitarThe miracle of volume! With its mahogany "long body" design and comfortable soft "V" neck, this faithful reissue of the 1930s classic sounds and plays like a million bucks. The vital feature of all Gretsch resonator guitars is the all new Gretsch "Ampli Sonic" diaphragm (resonator cone), which is hand spun in Eastern Europe from nearly 99 percent pure aluminium and yields an impressive quality and volume of tone.
