This is a Japan vintage Greco GOB-900. As shown in the pictures, the tuners have been replaced with GOTOH tuners, and the bridge has been replaced with a BADASS bridge. Also, this model originally had a mini-switch, but it has been removed, and the controls are now front/mix/rear selector, 2 volumes, and 1 tone. (I purchased it online 4 years ago, and it was already in this configuration, so I don't know the details.) There are also some dents, so please consider it to be in player's condition, appropriate for its age. The volume pots have some scratchiness. This instrument is almost 50 years old, so I hope someone who appreciates its value will adjust it and use it for a long time. The neck appears to be straight to the untrained eye, and the frets still have plenty of life left. I think it's in good condition for its age. I haven't touched the truss rod because I'm not an expert, so I don't know if it turns. Weight is approximately 4.6 kg. Comes with a generic soft case. I will pack it carefully and ship it. Since it is an old instrument, it is sold as-is, and I ask that you have it adjusted by the buyer after purchase. Thank you.
