This GJ2 is a nice and very well made guitar. Someone at JCF said they were built in the same factory as ESP/LTD, in Korea.
Since the Concorde models don't really sell well, you can get them at a decent price.
The neck has a C shape, which gets a bit strange on a V guitar. Low action, cool Habanero PUs, small frets, I like it.
The only thing annoyous was the Floyd (1000 I think), the trem arm was crap, so I put a Schaller arm on. Also I'd prefer a 42 mm block instead of a 32mm, but that' s details.
The piece of rubber is a "scoubidou" made by my daughter... sometimes she gives me things I like to hang on my guitars
