This is a G/D diatonic 'harp made of bubinga with redwood top and maple chord bars.
It has 16 chord bars, lock bars plus the usual I-IV-V7 chords plus relative minors and a
bunch of weird chords like minor-7ths and sus-4. Nice brilliant sound with full bass.
Oscar Schmidt fine-tuners except for the 37th string. I used
a set of strings from a cracked Wildwood Flower D-diatonic which Oscar Schmidt sent me
when they were out of stock on fine tuners -- so it has the extra heavy low D string and
a great low-end. Also has hold-away bars across the back to keep it off your chest
and thus improve the tone.
