One of those Copperbursts is currently living in my house; got it last week. FWIW, the leftys are Korean, not Chinese, and mine is
Flawless. Except for the D'addario strings, which will be going away as soon as the bass acclimates to being out here in the desert. The case I got with mine (a Kases guitar case) is pretty darn nice, too.
Dano lipstick pickups are very simple single coils; are the same for basses and guitars; and, since the Korean ones were reverse-engineered from original '50s pickups, are pretty low output compared to today's pickups. They are also very sensitive to height adjustments (my DC Pros certainly are); even then, the output from the bridge pickup is going to be low, because it's so close to the bridge. Sort of like a Rickenbacker. some people in the Dano Club over on Talkbass.com have experimented with a hotter aftermarket pickup there, but several have gone back to the original one after a while.
The rosewood saddle bridge? Always been a Dano trademark. Yes, there are adjustable Pro bridges (both my 1st Gen Korean DC Pros have them), and they are available, but most Dano afficianados prefer the rosewood bridge for the "Real" Dano sound. And yes, the Chinese bridges are notoriously bendy; don't know about the Korean ones, other than to say that the 20+ year old ones on my DCs are fine.
If you've never played a Dano Longhorn, you owe it to yourself to try one. They are a truly amazing, funky little animal, and a tool well worth having in your arsenal. Just be careful it doesn't become your go-to bass.
