Long-time G&L enthusiast here. My collection includes some USA models and a few Tributes.
The pics include my red Tribute Legacy, which is my favorite among my USA S-500 and Tribute Legacy HSS. The pickups and electronics are stock and fantastic. The bridge came out of a spare USA body I have, and it has a steel sustain block. I added the aftermarket brass saddles. I can't say to what extent the steel block itself changed the tone, but I can tell you that the saddles definitely did, and for the better. Check out that flamey neck, and that's a Tribute model!
The Invader has a DiMarzio Tone Zone in the bridge position and a Fast Track 1 in the neck. One mini toggle switch is wired for series/parallel and the other for phase in/out.
That cream-colored thing laying on the bed is just an empty body coupled with an unfinished neck, both of which are "2nds" I bought recently from the G&L webstore. The body is stupid light at 3.4 lbs. This is my new project build!
Cheers,
Jason
