This is a Headway HCF505. It appears to be a successor or higher-end model to the HCF18 and HCF 35 series. There is a dent on the top, but there are no issues as an instrument, and it is in very good condition. It is a flat-top guitar, but the back has an arch, so please consider it if you are interested. To my ears, the harsh metallic sound is suppressed, and it sounds mellow and smooth. I think it is suitable for those looking for a gentle tone. This item is only available on Mercari.
