I'm a DR guy... I have been since '98 or so. I've never had the QC problems some of you guys seem to have had.
I threw a set of Black Beauties on my ZON about 2 months ago, and it was friggin' HEAVEN... at first all I saw was "gimmick" but then I read an Ed Friedland review and decided to try them out for myself. I am TOTALLY sold on those strings. It's almost like they come "broken in" and they just stay that way forever... two months and HOURS of practice and gig time later, they're still sounding and feeling kickass ... and only some of the "black" has worn from the G string.
They're not even the new and improved "K3" coating either, which is supposed to last even longer.
On my Lull, my Custom Shop Fender, and my Stingray I use DR Sunbeams... best sounding nickle string I've ever found and those basses all sound best with nickle strings. They have slightly lower tension and last a LITTLE longer than a typical string because of the round core, but... they are spendy and don't last quite as long as I would like them to. Bass strings never do, though...
Not an Elixir fan at all... I've been part of a testing team for them a few times, and I dunno... when I very first tried them I dug it, but the more I used them the more I started to find their faults. Once the coating wears through, it'll actually start to "peel" and I've seen the coating frayed and hanging off my strings before.
The coating also insulates your strings from the ground at the bridge... so if you're playing an old passive single coil bass in a noisy room, touching your strings will not make the buzz go away. And if you're recording or listening through headphones, you can hear little grounding pops come from the strings as you play. I haven't experienced this with the DR coated strings.
They sent me another set to test a few weeks ago... I am supposed to test them for 8 weeks and I have to fill out surveys and stuff, and I can't wait to get them off and put on some Sunbeams.
Other strings I've tried that I like:
• Zon - pretty low tension, but they sound fantastic
• Warwick - totally underrated, but I wish they made a set without the tapered B
• Fender Bullets - as others have stated, these REALLY surprised me... I have a set on my fretless!
• GHS Super Steels - average tension, average feel, and average sound... totally average, but I have nothing bad to say about them.
Other strings I haven't liked so much:
• D'Addario XL - actually pretty decent, but too much tension for me... by the time they "break in" they're already dead
• GHS Boomers - are these dead out of the package or something? They sound lifeless to me... maybe I've had bad luck.
• Ernie Ball strings - sorry guys, but here's another one... I just bought a new Stingray, and along with the other problems it had, the strings sucked too... I'll post more on this once I get the bass back from warranty service
• D'Addario Chromes - Only set of flats I ever bought and it was like putting high tension steel cable from an pneumatic winch on my bass. I thought my bass was going to fold in half. I dunno... maybe I'm a puss, but I thought they were horrible. I do love the sound of flats though, so I need to try TI flats at some point.
I've tried a shit ton of other strings too, but they're not really worth mentioning...
