The Aquila 55C Ambra 900 is a normal tension set made for guitars built around the turn of the twentieth century: Torres-style and early Spanish instruments, and modern copies of them. Super Nylgut trebles give the warm, gut-like sound those guitars were designed for, and the Ambra 900 basses, wound on a multifilament Nylgut core, are gauged and voiced for the lighter construction and shorter sustain of that period. On a suitable instrument the set brings out a sweet, singing, historically convincing tone.
Aquila is a family-run string maker in Vicenza, Italy, best known for inventing Nylgut, a synthetic material that reproduces the density, feel, and sound of real gut strings without gut's cost, fragility, or sensitivity to humidity. For earlier romantic-era guitars see the Ambra 800; for a modern guitar, the Ambra 2000.
