Fernandes zo-3 Digital, offered as a junk item. I have confirmed power-on with a 9-volt battery, and the digital display works. However, no sound comes out from the amplifier when connecting a shield cable from the guitar to an amplifier. The circuit board appears to be in good condition, so I hope someone who can fix it after confirming power-on will take it. There are scratches and dirt overall, giving it a relic-like appearance. The neck has a dark color and looks cool. This is a junk item, so please understand that it is non-refundable and non-returnable.
