Aquila 5B New Nylgut 5-String Banjo Strings Medium Tension

The Aquila 5B is a 5-string banjo set that takes a distinctly different approach to the same acoustic challenge addressed by the Red Series - using Aquila's proprietary New Nylgut compound, with a Red Series 4th string for the lowest note where the density advantage is most needed. New Nylgut is not common nylon, carbon (fluorocarbon/PVDF), or a blend of them - it is a precision plastic compound of three different components, engineered to achieve a density similar to pure gut at approximately 1.30g/cm3. That higher density is the key to its acoustic advantage: compared to nylon, New Nylgut strings absorb far less moisture (less than 0.1% versus nylon's 2.0%), meaning tuning stays more stable across varying humidity conditions without the metallic character of carbon strings or the low-volume warmth of standard nylon.

The result is a set that stays in tune faster, produces a richer and more gut-like tone with better sustain and note definition than conventional synthetic banjo strings, and maintains consistent intonation across the full length of the fingerboard. The Red Series 4th string completes the set where the extra density of the copper-impregnated compound is most valuable - ensuring the lowest string matches the brightness and responsiveness of the upper four. Ideal for acoustic and old-time banjo players who want the warmth and organic character of gut strings in a durable, humidity-stable synthetic package.

Features

• New Nylgut compound - a precision blend of three components engineered to match gut density (1.30g/cm3) - delivers richer tone, better sustain, and more accurate intonation than standard nylon or carbon banjo strings.
• Moisture absorption of less than 0.1% versus nylon's 2.0% ensures exceptionally stable tuning across varying humidity conditions - a meaningful practical advantage for performing banjoists.
• Red Series 4th string with copper powder impregnation provides the extra density needed for the lowest string to match the brightness, responsiveness, and tonal balance of the New Nylgut upper strings.
• Natural gut-like tone without the inconsistency, fragility, or expense of real gut - producing a warm, organic acoustic character that suits old-time, folk, and classical banjo styles equally well.
• DBGDG standard 5-string tuning in medium tension for comfortable playability and reliable response across all positions.
