The lightest I've ever owned was a gibby flying v medallion, the one you hear on Aeronautics, was lighter than just the hardware alone should have been
Im in the parker fly camp too, I hit myself in the face with one the first time I picked it up thinking it was gonna be heavier than it was. Ibby's are my shit though but the parker is just an insanely comfortable guitar.
I got my S-470 used about 8 years ago and it's held up just great!! Very thin and lightweight....but if you stand around at practice for a few hours with it over your shoulder, you WILL feel it.
yeah, but after a few hours practice, you will feel almost every guitar as long as it doesn't weight nothing..
I wasn't sure about the budget, that's the reason why I didn't mention Parker, tried a few of them, loved them
but the price is just out of my range for the ones I liked.
Not sure about Blackmachines, but they're pretty thin afaik so I think they could be light, too.
