String Diameters in inches 1st-6th:
.025 .028 .034 .030 .036 .044
The Corum strings use the Alliance trebles, but the basses are created with a different winding process that seems to extend their longevity and improve their intonation.
The Blue Card is their highest tension (equivalent to Yellow for their Traditional line). The Blue basses tolerate a louder dynamic than the Red but sound quite similar. Also, the tone color of the Blue 1st string is fairly distinct from the 2nd and 3rd though not so noticeably as with the Reds. Otherwise, the two tensions are fairly similar.
Basses: The tone color of these basses is rich and warmer than the Alliance though their projection is still excellent. Their longevity is good, and the intonation is reliable. They allow for plenty of color variety and subtlety of vibrato.
Trebles: These are probably the thinnest of all the strings we carry. If you are looking for a cutting, brilliant treble, these are good candidates for you. Their response is extremely quick. They are very smooth and not as stable under the fingers as most other brands, though the difference feels negligible to many players. These strings are good examples of a brand that sounds very good on some guitars and quite a bit weaker on others perhaps because of their emphasis of one color.
