Funny that this came up-- I just went through exactly this exercise recently comparing both D'Addario Chromes
and Thomastik JF344s on a couple of basses. I was hoping the Chromes would be a good alternative since they are indeed cheaper. I'd agree that Chromes are great for an "old school" player who is used to rounds and "Fender type" flats (which are definitely higher tension than the Chromes). But I'd be careful about comparing them to Thomastiks. The string construction is very different; Thomastiks have a small round core, silk under wrap and soft nickel wrap vs. Chromes larger hex core and string diameter. As a result they don't sound the same, and Thomastiks have quite a bit less tension and are more pliable/flexible, which makes a difference if you haven't developed much finger strength yet; if you're just starting out Thomastiks would be easier to spend extended periods on time practicing on. There's a good thread about this topic over at Talkbass if you want to get some additional opinions...
http://www.talkbass.com/forum/archive/i ... 66305.html Depending on what strings you're currently using, Chromes may also require adjustment to compensate for increased tension (not a problem if you know how to do a proper set up or having a shop put them on, but as someone who comes across hundreds of basses I'm amazed at how many times the action is near unplayable, and I wonder how many novices give up on playing bass as "too hard" without ever realizing their instrument isn't properly adjusted).
PJ's suggestion about coated roundwounds isn't a bad idea either. I don't really care that much for the sound of any coated strings, but I would also endorse Elixirs as the best choice in that category.
Frankly, strings are one thing we all wish we had access to more information on. It can be surprizing how much they can add to or detract from the personality of a particular instrument in terms of both sound and playability. I still have several basses that I've bought used that I LOVE the strings on but have NO idea what brand of strings they are!! I highly recommend anyone picking up a copy of Bass Player Magazine March 1996 Strings Special Issue (there's usually a copy or two up for sale on ebay)- very helpful reference tool for comparisions of many of the most popular strings.
