The Nantel Verdict
The Nantel Verdict
Flat wound construction delivers ultra-smooth feel and finger silence; XL Chromes formula produces dark, warm tone with extended sustain; super long scale (0.105"-0.132") accommodates deeper tuning ranges and increased tension; regular light gauge balances playability with tonal presence.
Super long scale fitting required—verify bridge pin compatibility. Ideal for 35" scale instruments; check headstock geometry for string clearance. Flat wounds require less frequent replacement than rounds but demand gentler technique to preserve surface. Setup adjustment may be needed after installation.
D'Addario's XL Chromes define the flat wound standard for controlled warmth and whisper-quiet playing. These super long scale sets anchor lower tunings with composure, delivering the sonic character that defines classic rock and contemporary jazz bass work.
