This is an Ibanez 2350 Les Paul Custom.
I am not familiar with guitars, so I asked a friend of mine who loves musical instruments to check it out for me.
The serial number is F77, so it is a Japan Vintage Les Paul Custom made in 1977.
This is a rare model that is rarely seen in Japan as it was made for export.
This model is still very popular in overseas, and it is priced over 100,000 on REVERB.
It has a chambered body and bolt-on neck, which is different from the original model, but that makes it unique and popular.
The SUPER70 PU, which is said to have been used by Eddie Van Halen, is also highly regarded for its brightness and pleasant outgoing sound.
String height is about 2.0-1.6 mm on the 12F 6-1 string.
The neck is straight and the frets are about 60-70%.
There is a chip on the logo area as shown in the picture.
It is a fairly easy guitar to play, although there are some dings and dents.
