" The EJ45TT normal tension set is D'Addario's lightest tension of out of the Dynacore family. Laser selected titanium trebles paired with a flexible composite core in the basses come together to produce a truly remarkable set. The new (2012) Dynacore basses are winded using a revolutionary technique.
Players who prefer rich tones along with projection will favor these basses. The trebles produce brilliance and projection. As a full set, the basses and trebles work together and compliment each other achieving tonal balance.
We find these strings to be quite bright overall. The titanium trebles have a bright, edgy sound that seems to work well on spruce top instruments especially and the new Dynacore basses are very powerful with very present overtones. The bass strings have a very supple, elastic quality to them rather than the typical stiff feel that many bass strings have. Just a note: these basses are not the same as the ones found in the Composite or EXP sets, those are very different in sound. The Dynacore basses are slightly warmer than the Composites, and possess a much nicer, more neutral timbre compared to the very bright, mid-range focused Composites. " -Strings By Mail
