Since I think at the moment I'm the only owner of a 7 string baritone(RG 7680LTD-1) I'll write few lines about it.
First of all the neck is totally different in the aspect and construction from the XL series
mine is a five(5) pieces maple bubinga with the
scarf joint, the headstock is the same color as the body, with that strange effect due to the paint job, the dots are centered and every single binding and dots glows in the dark.
the rest I think is pretty much the same hardware wise
Since I picked this baby up in Italy2 months ago the other members of my guitar family are always in the cases, the main advantage from the standard scale is that you can have 09s and still have the seventh string very present and not sloppy even if you detune, the downpoint is that in the lower positions is a tad more difficoult to do complicated chords but at the opposite is a dream to play in the high registers, it's only a matter of streching a little bit more the fingers in compex chords
If everything goes well I'll be at JEMFEST with the new baby in few months
Sincerely
Stefano Giusti
