As a BC Rich fan, *most* of my stable are purportedly "neck divers" but none of them are that bad really... at most diving parallel to the ground if I take both hands off. Keep in mind that I do use a wide, suede backed strap with all my basses.
The worst I own at the moment is the silver Ironbird, but I've yet to move the front strap pin but not too bad.
my other two are fine actually, the white NJ series is all maple so no issue at all with balance with pins in the standard spots. Moved the front pin on the mahogany one because it was kinda bad at first, now its good.
My mockingbirds are both well balanced, both all Koa maple stringers so incredibly light weight(the blue one is better balanced despite an even shorter upper horn). Waiting on new electronics
The absolute worst neck diver I ever owned was the Gibson "blackbird"(nikki sixx model). This was me playing 1st Ave in Minneapolis, I owned it for a whole year, moved the strap pins, used a suede backed strap but couldn't remedy the balance issue. My left hand would cramp up constantly....
I find it amazing that there are people who up and down deny that *any* tbird is neck heavy?! I don't doubt that there are plenty that do balance well, but that wasn't my experience at all. I do regret selling it, but only because of the "blackbirds" tone (piano like clarity).
Anyways I finally sold it and got into BC Rich handmade basses(I had a cheapo platinum series in HS which was awful) which are perfect for me. Love the look, the tone and the feel, they feel like an extension of me.
