DR Sunbeam Acoustic Phosphor Bronze

SUNBEAM phosphor bronze strings are hand wound upon round cores which
gives a terrific result: wonderful sustain...remarkable sustain.
The tone does not decay as do other phosphor bronze strings,
which we think seem to sustain in a straight line, until the sound
"falls off". The SUNBEAM acoustics are musically bright and rich sounding.
Additionally they are very flexible...more so than any other string we have played.
