-according to serial number (U00010760):

Unsung Plant, Korea
on January, 2000
Production Number: 760

there is the same guitar in the picture ,

 

It looks to be a Korean G-400 Custom, just like you said. Hope you enjoy her!

 

Yep, a Custom.

Welcome here and where are you from ? Make sur to show us real photos of your new guitar.

 

Thank you, im from Hungary

 

Really nice. How does it sound ?

 

It sounds really nice , THe stock epiphone 57pickups are awesome

This is a rare g400 custom guitar With these tuners? i didnt found it on the internet With this U se rial and this type of tuners

 

Someone could have swapped them at one point. Also, sometimes different runs of guitars coming from different factories can have different hardware than what the original specs state. My TV Silver G400 Pro came with Grover tuners but the specs say Wilkinsons with tulip buttons.
