hey guys, trying to determine if the old j50 is a fake Gibson. no serial number , no label, bridge has been changed or never was an adjustable . guitar has 3 dots on the fret board below the 12th fret which i hav not seen before. guitar sounds amazing can't seem to upload any pictures for viewing . get error message saying file to large , just a photo so not sure what is going on with that. any help would be appreciated
