Banjo tuners blow dogs for quarters. My 96' I still have and my 98' and 76' which are long gone have/had them. The ratios are too low and they are HEAVY. The regular neck through body Firebird reverse guitars are very neck heavy anyways. To the point when you let them go with a strap on them, they dive headstock first towards the ground. Not comfortable to play for an entire gig. I loathe 99.99% of any new Gibson guitars, but the new Firebird tuners are alot lighter much more practical. plus on the Firebird V, the still stick out the back. The Firebird I just got has Explorer style Grovers. The headstock is non-reverse like a 1965. transition model. Much easier to tune, and way lighter.I'm still a Gibson fan, just buy older ones. Why do you think they changed from banjo tuners on the Firebird? I think it changes the look of the headstock.
Pictured is one of my unicorn guitars. A 1965 Gibson Firebird III transition model. Notice the headstock and tuners, and how to new 2018 Studio P-90, pay homage to this without costing $18-20K
