PIG NOSE Built-in Mini Guitar PGG-100T Brown Sunburst Comes with a dedicated soft case This is a very rare model equipped with a tremolo unit. The following have all been tested and confirmed to be working: ・Built-in amplifier ✅ ・Connection to an external amplifier via a cable ✅ ・Headphone connection to the earphone jack ✅ As you can see in the photos, there are no scratches or rust, and the protective seals on the pickguard and covers are still in their original condition, making it a nearly unused, beautiful item. At the time, I bought it hoping my son, who was in the upper grades of elementary school, would become interested, but he never showed any interest and hasn't used it since. ※The guitar stand in the photo was only used for photography and is not included.
