An ideal string to solve the issue faced by roots bassists who want strong and defined pizz but also want a natural woody click when slapping. This A, and the similar E, provide tonally perfect match with plain gut or synthetic G and D, while also giving a subtle and balanced click when slapping.
Only downsides: The click is very slightly more clinical and metallic than plain gut, but significantly less so than other strings often used in this way. Also, the open E and A, on my bass, deliver slightly less fundamental thump than plain gut or some other wrapped synthetic strings. The overall effect of this is that the strings sound fractionally weaker and thinner.
These strings are most similar in tone and tension to Innovation Braided Solos when played at concert pitch.
They offer a fantastic compromise and alternative to plain gut or synthetic A and E, , trading a little overall depth and thump for a precision and articulation normally found only with steel strings.
