I got them when I needed them.

Rich Warm bottom, Bright top

These are fantastic strings. They're in my top 3 favorite strings. I tend to switch between these and DR Pre-Alloys (Medium Heavy gauge on both) a lot because I haven't figured out which one I like better.

These have a very bright, cutting top end. They're great for bluegrass for that reason, although sometimes I feel like they're just a tad to bright. They do warm up a little more after a bit more playing than it takes to initially break them in.

The low end of these strings is what gets me. It is incredibly warm and rich. It's a gorgeous sound.

I find these work best for finger-picking and soft strumming.

Depending on which box, what I plan to play and the action I need, it often dictates which strings I use. These are great especially for low tunings. Of course, the tone is great otherwise I wouldn't even be writing here......

For fingerstyle, I find they work great on my 000.

These phosphor bronze strings have a great balanced tone, bright on the high notes, and deep clean bass on the low notes. For the gauge, they play and bend so easy, you would think they were light gauge. Great volume, loud, and the tone lasts for longer than any strings I've ever played. (And I've tried 'em all over the last 33 years of playing acoustic guitar.) Highly recommended for the Bluegrasser or Fingerstylist. I play 'em both ways.

" ' SUNBEAM' phosphor bronze strings are handwound upon round cores which give a terrific result… wonderful sustain…remarkable sustain. The tone does not seem to decay as do other phosphor bronze strings, which we think of as decaying in a curve. The 'SUNBEAM' phosphors seem to sustain in a straight line, until the sound 'falls off.' The 'SUNBEAM' phosphors are also musically bright, and rich sounding. Additionally, they are very flexible… more so than any other string we have played.

DR Strings

"From the first handmade strings DR made for Marcus Miller and Jeff Healey (both of whom have played DR's for over six years), to our latest development, the remarkable ZEBRA electric-acoustic strings, DR HandMade Strings approaches sound and string design differently from other makers… we are all players. The secret to the way we make DR strings is the word "slow." No other company we know makes strings one at a time, so very slowly and carefully. Quality of sound is paramount… along with the highest possible specifications for materials. Longevity and durability are our next concerns. We are NOT a high speed, mass production company. We have an elaborate quality control system.

For a relatively new company, we have been embraced by a surprising number of "Legends and Masters" of guitar and bass. A partial list of DR endorsees includes Sting, Marcus Miller, Jeff Healey, Adam Clayton of U2, Warren Haynes of GOV'T MULE and THE ALLMAN BROTHERS BAND, Jonas Hellborg, Bo Diddley, "Skunk" Baxter, Victor Bailey, Steve Kaufman, Percy Jones, Darryl Jones of THE ROLLING STONES, Rick Derringer, Mick Karnes, Andreas Kisser, Max Cavalera, & Paulo Jr. of SEPULTURA, Birelli Legren, Trey Anastasio and Mick Gordon of PHISH, SMASHING PUMPKINS, Gary Tallent, Tony Franklin, Ty Tabor & Doug Pinnock of KING'S X, Dimebag Darrell of PANTERA, Scott Ian, Paul Crook, & Frank Bello of ANTHRAX, Stefan Lessard with THE DAVE MATTHEWS BAND, Peter Rowan, Shawn Lane, Paul Pesco Matt Freeman with RANCID, Per Gessle of ROXETTE, Sharlee D'Angelo of MERCYFUL FATE, and VERUCA SALT.

DR Strings are made with more metal than one realizes at first. By way of example, before a .042 gauge DR string is carefully wound, core wire and wrap wire that total .043 are prepared. After a process we call "Compression-Winding", a DR string that gauges a .042 is produced.

The ratios and principles of "TITE-FIT" / "Compression-Winding" are used for the specifications and manufacture of all DR strings. At DR we craft our strings at tension. The following is one example of how the DR wrap/ratio formula works… in this case for .042's. Core wire is .016, wrap wire is .0135 x 2 (top and bottom covers). Total material gauges .043 before winding and .042 after winding."
