SANSO Lyre Amane 37 strings / Range: E - e'' (Mi to mi) Chromatic scale (12 tones) Sound hole for resonance: None Size: Approximately 600 x 400mm *Thickness of soundboard body: approx. 42mm Weight: Approximately 2.35 kg Material: Basswood core, semi-double-sided Frame: Maple + Poplar Color: Walnut Accessories: L-shaped tuning wrench, soft bag *Hard case not included All strings resonate properly. I have maintained the strings when they have rusted. It does not affect the performance, but black spots remain. Please refrain from purchasing if you are concerned. Please check images 9, 10, and 11. I am listing this for those who are looking for one. I have marked it as "Slightly scratched or dirty," but there are no noticeable scratches on the surface, and I think it is beautiful, but for those who understand that it is a used lyre. *Because it is an important instrument and an expensive item, we reserve the right to refuse purchases from those with low ratings.
